For some reason I can't upload the mod to enable this for the drukhari, so I'm putting the steps here where you can create your own no loyalty penalty mod for them.

1. Go to your My Documents/Proxy Studios/Gladius/Mods folder, and create a folder in there. Name this folder whatever you want the mod to be called.

2. Go to your C Drive(or whatever drive you have gladius installed on)/Steam/steamapps/common/Warhammer 40000 Gladius - Relics of War/Data folder.

3. From here, you're going to want to go to the World/Cities folder. You should see XML files of all of the factions. You can do this for any faction, but for this specific guide we're touching the Drukhari.xml file. Copy this file, don't modify or delete it.

4. Go back to the mod folder that you created in the Mods folder from step 1. Put a new folder in there called Data, then put a new folder in Data called World, and finally put a new folder in World called Cities. This is to mimic the format from the game's files. Paste the xml file you copied from step 3 into here.
So it should look like this:
(your mod)/Data/World/Cities/Drukhari.xml (or whatever faction xml you put in there)

4. Open that Drukhari.xml file in your mod with a text editor of your choice, I prefer using Notepad++.
You'll probably see something that looks like this, if you're doing it for drukhari:

you're going to want to put this block of code under the first <city> line:

The end result should look like this:
And from there you are set! Save the file.
5. Now all that's left to do is launch the game, go to Extras, and enable your mod. I'm not able to test if this works as I don't own the drukhari dlc, but I have tested it with other factions and it's always worked for me there.
Feel free to ask me any questions if you get confused or need help! :)
