Lemme answer some of these suggestions with things that are already explained or shown in-game:
-Undead clans: That could be the Children of the Last Gasp (or whatever they call themselves);
-Farm girl laying and/or incubating: I don't know if it's really gonna happen. In-game there's an explanation that only the royal line (aka Princess Adeline) can give birth to true dragons, so probably not happening unless it's half-dragons (or whatever comes out of non-royals) that you want;
-Autosave and whatnot: I mean, you can always save before choosing an option if you think it might kill you. By the way, how is going back to the menu after a death an issue?
