We’ve put quite a number of hours into Endless Space here in the team at Mana Pool and during this we’ve ran into plenty of things we’d like to tweak or see done in a slightly different way. The Endless Space developers have been so kind as to support modding in an active and extremely helpful manner, which just begged to be used. As a result, we present Imperium Aeterna – which roughly translates to ‘Eternal Empire’. Our goal is to maintain the vanilla ‘experience’ as much as possible, but to enhance our enjoyment of the game with enhancements and tweaks over time. This mod will grow as we gain ideas and or incorporate other mods and could become as little or as large as necessary to enjoy the game to the fullest.
Anyone is free to download, play and use the contents of this mod in their own mods – provided that full credits are given accordingly and a link to this page is added.

e.g.
C:Users\Your User Name\Documents\Endless Space\Disharmony\Modding - Place the entire ImperiumAeterna folder there.
e.g.
C:Users\Your User Name\Documents\Endless Space\Disharmony\Modding\ImperiumAeterna
C:Users\Your User Name\Documents\Endless Space\Disharmony\Modding\ImperiumAeterna\Index.xml
C:Users\Your User Name\Documents\Endless Space\Disharmony\Modding\ImperiumAeterna\Folders - In Game – Go to “Mods” and select Imperium Aeterna.
When you re-launch Endless Space, the bottom left of the title screen of the game should show you the version of Endless Space you are running, with the version of the Mod right below it. Have fun!
Updating to a New Version
Updating is extremely straight forward, but here are explicit instructions for those who asked
- Delete the ImperiumAeterna folder in C:\Users\Your User Name\Documents\Endless Space\Disharmony\Modding
- Place the new ImperiumAeterna folder there instead
Save game compatibility between versions is not guaranteed. Generally speaking, each “full” number is not going to be fully save game compatible. E.g. 2.1.0 won’t be savegame compatible with 2.0.0, but 2.0.5 might be.
Uninstalling or Disabling
Disabling the mod is incredibly easy. None of the original game files are ever touched, so this is perfectly safe.
If you wish to play Vanilla:
- In Game – Go to “Mods” and select “Endless Space”.
To play the mod again, simply switch back.
If you wish to Remove the mod permanently, add the following step:
- Delete C:\Users\Your User Name\Documents\Endless Space\Disharmony\Modding\ImperiumAeterna

Imperium Aeterna incorporates the following mods either partially or entirely:
Orbital Entrenchment Mod by Igncom1 – Provided the initial basis of the 4 ‘orbital’ technologies and their improvements. The version used in Imperium Aeterna has evolved a lot since then, undergoing re-balancing, bug fixing, custom tech icons and more.
Colored Anomalies by Luminality – Incorporated entirely. We’ve made extremely minimal modifications to this mod, mostly to make text easier to read.
PlanetSize Terraforming by Tiaximus – Incorporated with small modifications to costs for balance reasons.
Anomaly Overhaul by Tiaximus – Incorporated all new Anomalies.

Please leave us some feedback, we love to hear from you! :-) If you like the Mod, please consider sharing it using one of the buttons below.
Best of luck!
Just hope my initial coding for the orbital entrenchment was ok!
It was more than ok Igncom1 :) When I ran into that, it inspired me to start looking at the modding side of things. I literally started the process by adjusting your mod and things continued from there.
The idea is hopefully to assimilate more good ideas I run across from other modders, as well as add any modifications I come up with myself.
We don’t want to dramatically change the game, but if that’s what it takes to make our gaming sessions more pleasant then that is exactly what we will do.
We play the game extremely regularly in Multiplayer right now with the same group of people, so we’re getting a good idea of the aspects we feel could be improved. We’ve already felt some very positive effects from the changes!
v1.4.0 released!
Time to catch some sleep :-)
v1.4.1 released :)
v1.4.2 released.
v1.4.8 released.
v1.5.0 released.
Between the new ES patch and this mod I am looking forward to playing ES again, it beats CIV5 now. I like ALL the ideas you’ve incorporated and hope some of the ideas end up in the actual game(color coding being #1!) Thanks.
Very glad you’re enjoying the game and the mod. A lot of the active modders are also part of the VIP team on the Endless Space forums, and help the developers with upcoming patches and add-ons (testing, feedback, etc.) – myself included.
The developers are very responsive to ideas from the modding community and are certain to pick up elements that are extremely popular among the player base. If you are enjoying the game, it’s definitely worth voicing your opinion :)
Thank you EvilTactician and everyone else who contributed to this mod. I hope to see it grow and get better, almost perfect…
Thank you again.
Respect.
Thank you for this mod, really makes an enjoyable game even better :)
Is this mod compatible with 1.0.46? I ask cause planetsize terraforming doesn’t work it changes the size of the planets but not the population also a slightly more major thing the AI builds no combat fleets (only scouts and colonists) and they stockpile dust.
The population capacity changes, not the population itself :)
The fleets issue is a reported bug on the official ES forums – it’s something that puzzles both me as well as the devs, we haven’t found the root cause as of yet and aren’t even sure it comes from the mod :/
Loaded the save and tried the Terraforming again and it did not increase pop cap HOWEVER started a new game without crowded planet trait (+2 tiny/small +1 medium) and now it does work so either I’m missing something or the trait and Terraforming does not work together.
Also tried some of the “fixes” from the forum thread no luck yet with AI fleets.
I did notice something interesting though, the original ships the ones that one starts with as well as the original designs do not have your weapons/defense but rather vanilla modules not sure if that has anything to do with it…
I will keep trying somehow i will find a way to play this mod I’m really looking forward too it :)
Great mod! Brilliant! Its a must to have it! Unfortunatelly i had downgraded to version 1.4.9 due to no AI fleets problem.
Anyway, speaking about new ideas, how about moon creation technology? Can you guys do something with heroes? Simply most of them are useless in vanilla version.
Finally I wanna ask, does exist any community modding site for endless space, I mean something like Nexus modding comunnity site? I think it would be great idea to talk to them to start endless space modding site on Nexus. Somethink tells me they don’t mind…
Thanks again!
Seems like there is a little problem with the Sowers. They have an unique technology “exotic thermodynamics” which lacks an ability to increase planet size from medium to large, preventing them from enlarging all the planets in the universe :)
// Enlarge your tundra
Update to my previous comment (don’t think that this update needs to be approved and posted though).
Indeed, there is missing block in “SimulationTechnologyExpansion.xml”. Comparing with original .xml there should be added something like this:
$(AffinitySower)
TechE09;TechE09WithColonizeTraitScience03
%TechE20SowerTitle
%TechE20SowerDescription
Damn… Styles won’t go through the posting form. Well, ok, just will post it here: http://udginvr.mass.hc.ru/tmp/TechnologyExpansion.xml
You just needed your first post approving manually, that’s all :)
What does the modification to power in some of the hulls do?
Hi
I’m getting an issue that when I start a new game an error message pops up and when I click to continue playing there is no universe, only the background.
Pls help, thanks
Thanks for a great mod :D
I just wonder if this mod is updated to latest version of ES?
Well this mod doenst work on Disharmony expansion!
everytime i get a nullpointer error and the game freezes.
I followed all the instructions, but every time I load the game, I do not see the mod at all, only the classic (version 1.1.17). Is there anything else I can do??
The mod has not been updated for recent game versions, sorry.
I see that this excellent mod is not updated to the new versions of ES such as Disharmony, but will it be or is this a dead project?
Then update it.
Whilst I can understand that an abandoned mod can be quite frustrating (I’m a gamer too in the end), please do bear in mind that no modder is ever obliged to update their mod or well, to do anything at all. Whilst I am currently updating it (finally, I know..) so far this has taken me over 20 hours and I expect to put another 20 in just to get the mod fully compatible in a way I’m happy with. It’s by no means a small task and it requires an amount of free time which I simply didn’t have in the last few years.
Long story short, a small amount of appreciation is appreciated. I’m am however updating the mod as I had no idea it would become as popular as it did and I feel bad for it being in the state that it is. Bear with me.
Just started a game with this, event text seems to be missing from events now. Any way to fix that?
I can’t really see why the mod should have caused that, but easiest way would be to wait for the new update, which is coming soon.
how can i change the weapon tier every weapon is stuck to lvl 1 . is it a part of the game or a bug
The mod is not compatible with the game version you are trying to run it with. I’m currently looking at resolving this.
This is a rather late response, but I will look at resurrecting this, provided that is doable as a lot of things changes since I made this mod.
Working on it!
Great point and absolutely an oversight in 1.5, I will correct this for 2.0 – which is coming, I promise!
A really late reply, but I wanted to address this nevertheless. I’m a fair bit more knowledgeable now and I think I know what happened in both instances.
Terraforming: When increasing planet size, it essentially ceases to be a tiny or small planet – and thus will lose the associated bonuses from the trait. I may have to change the trait so you get a bonus on any planet, otherwise the trait will become pretty useless in this mod.
E.g. Terraforming a Tiny Planet to a Small planet, gives you whatever the size increase is from that but DROPS one population from your trait, as the planet is now small (+1 bonus) instead of tiny (+2 bonus)
Terraforming again to Medium, will make you lose the trait bonus altogether.
This means the trait would only be useful in the early to mid game, after that it will lose all value as you can ‘simply’ increase the planet size. That’s a byproduct of the game mechanics I’m afraid.
For the original ships, the weapon and defense modules in Imperium Aeterna 1.5 and earlier are ‘unique’ as far as the game code is concerned. The ‘old’ ones still existed too and I never updated the modules that the starter ships came with. It’s a really good spot!
I’m rewriting most of the code when it comes to combat and modules in the next few releases, so these kind of issues should stay in the past.
Version 2.0.0 has been released. This enables compatibility with Disharmony 1.1.58 (the latest version). Classic is NOT supported, by now everyone should have the DLC really and we don’t want to support two versions at the same time, given how fundamentally different the game is in Disharmony.
We are also working on the next version of the mod. Expect more weapons, more defense modules, more balancing and quite possibly a few entirely new features.
Version 2.1.0 has been released.
Introducing:
=> Tweaked Diplomatic AI to lessen the Frenzied and Illogical Aggression in Disharmony.
=> Overhauled Diplomatic Relationship progression and added 2 more relationship statuses.
=> New icons for Planet Expansion Terraformations, created by bigbantha.
=> New icons for Planet Creation, created by Cosmocrat.
=> Added Planet Colours to Tier V Planets (Gas Giants and Asteroids) for consistency.
=> Added Planet Colours to Xenotourism Agencies Tooltip for consistency.
=> Added Planet Colours to Deep Space Facility Tooltip for consistency.
=> Added Planet Colours to Colonization and Terraformation Tooltips.
Version 2.2.0 has been released.
Introducing:
=> Added Gaia Planets and Gaia Terraformation.
=> Added Unique Planet “Aeterna”, with its own Wonder, Temple and Events.
=> Added 62 New Anomalies from Tiaximus’ fantastic Anomaly Overhaul.
=> New icons for Orbital Technologies and their improvements, created by bigbantha.
=> Orbital Trade Hub bonus “+1 Population” changed to “+1 Trade Route”.
How can I install this on a mac?
Pretty much the same instructions, except you find the right folder here:
Go to “User LibraryApplication SupportEndless SpaceDisharmony”
All other steps should be pretty much identical, just the location of the modding folder is different :-)
Hey, great mod so far, but is it normal that i have only one phase working in manual space battles, the 2 lasting rounds, both side don’t shoot anymore, is it part of the change in the combat ? Or is it just a “graphical” problem ?
All phases should be working fine – if this isn’t the case, could you please visit our mod forum at http://www.imperium-aeterna.co.uk and report the bug. Please include a save game and a detailed description of the issue.
It would be very helpful to know what weapons you and the opponents were using, as well as the battle cards played.
I’ve heard of this issue before in another mod, but never in Imperium Aeterna. Are the ships still receiving damage? Perhaps it’s an issue with rendering the visual FX on your computer?
Hi, this mod looks great, but every turn i am forced to assist a random battle that im not involved… only option is to go to desktop… this bug
is irritating…
the battle is between 2 Hunters and a scout! thats not mine…
Hello nice Mod! Small question did someone have translated the xml files in French ?
Hi Eric,
This is quite an old mod now, and I don’t believe it was ever translated to French. I was working on additional features and do have more assets, balancing, events, etc. in a development version but I got stuck on something and the developers (Amplitude) promised to provide some assistance/answer but then never did. As a result I had to abandon the work. It was quite disappointing, really..
Ok sad news anyway I don’t play anymore and believe all works now is on endless 2. This is some sort of big mod merging anyway
Hi, I’m just wondering if there’s a place where you guys have posted, in detail, the exact things that the mod adds? I want to be able to know exactly how the AI diplomacy was changed, the exact anomalies and what they do that were added, etc etc. Thanks in advance!
Very late to the Endless Space party, but I made it. This game is so much fun I may buy Endless Space 2 as well. Thanks for the mod.
Heya if any one is reading this i found a bug. The enemy cant use the tactical cards (eg weapon overlock or retreat) if theres any fix to it please reply
Definitely not related to the mod.
