Dark side - Heroes atom files

[Crendagord]

Hello gamers!

I'm currently playing with Neoline but I don't like the original model so I've decided to replace it with the succubus. I've managed to find and extract the succubus models and animations. It works well when renaming these files to Neoline's

Now I would like to directly modify her atom file but I haven't found it yet. For those who are interested, the atom files of the two other heroes are here:
- Bagyr: hero_olaf and hero_main in "data\data.kfs"
- Daert: hero_olaf_2 and hero_main_2 in "sessions\darkside\ses.kfs"

I'm used to mod Oblivion, Skyrim and Age of Mythology, but it seems to be quite the mess for the KB series (I've bought the full collection on Steam)

So I would appreciate a hand to understand how these games work. Is there a list of atom files, creatures... and so on?
