I think Fatt_Shade already replied, but the reason why is that in my mod for the Legend, the children that you have become the heroes in Heroes of Might and Magic III!
So they grow up and go into a time warp and arrive in Erathia / Enroth, etc. and go on to perform the tasks in HOMM3 that I grew up playing and really enjoyed. So, for example, Gelu is really the son of Neoka and goes on to partake in the Armageddon's Blade expansion of HOMM3.
So that's why it is called HOMM3 Babies. Now that I'm porting it to AP / CW, there are no babies that you can have in those expansions, so instead the babies are now tomes. The tomes describe the stories of the children that your hero and the various wives of TL had as they play them out in HOMM3 and its expansions.
These tomes are essentially items that you can equip on your hero that have similar bonuses as to their bonuses in HOMM3, except changed where there is no equivalent skill / unit in King's Bounty.
I really apologize for the long time it has taken, but there is only so much time in the day to work on it, and really I'm working on 3 mods simultaneously, and it requires playthroughs to ensure that everything is working.
The fact that WotN is so buggy, you can see how long it takes to develop quality expansions / mods for KB especially when modding the LUA files.
TL, AP, and CW are different enough that I can't just port the functions over and be done. I have to essentially play test everything and just because an idea works during the first test, there are situations where it may not work in other situations.
I'm almost done with my current TL playthrough with my H3B mod and then I plan to get back to H3T for AP / CW, but I've learned quite a bit and have some ideas now to aid in co-developing 3 mods simultaneously as well as how to implement the hero items properly.
So I hope that you'll be patient with me...
