If you guys want to edit the unit avaiable in shop you need a tool called KB database editor. It decode the game files databases, namely *. act, *. chat, *. hero, *. loc, *. lu and *. qst. To edit the shop you need to edit the file *.embryos.loc for each region, ie: debir.embryos.loc, shatterra.embryos.loc. After the file has been decoded to text file, open it and search for the phrase "{A}{class} = {castle}" and look up, it's the key word to end a shop data. I'm sure from now you will figure how to do it because it's quite simple. If you have any trouble just ask here, i may help but don't expect much because i'm also new to it
. I have uploaded the mod i made as an example, I also reup the tool or you can find it in this link
