So I'm working on a mod with somebody else and there's going to be corrupted versions of some creatures. For wildlife like bears and wolves we're just making them normal creatures that are quite rare, but with megabeasts we were hoping to do something a bit more interesting. It's obviously an option to just have the corrupted megabeasts be corrupted at the start of world generation, but we wanted to see if there was any way for it to potentially happen during world generation which would make it a lot more interesting if they had a history before being corrupted. Anyway, as for the ideal way of being corrupted, it would be to be captured by a rare leader caste of an evil civilization and then corrupted. Does anybody know any obvious ways to do this? I was thinking it could be something with night creatures, which might make them ineligible for leading civilizations, but it could have [SPOUSE_CONVERTER] and there'd be a caste for the different megabeasts. However that leads to the problem of how to make sure they don't capture humans and turn them into corrupted dragons, and whether megabeasts even could be captured if they had [SPOUSE_CONVERSION_TARGET]. This doesn't have to be the way they're corrupted though, so if there's any other good ways to have a historical figure change into a different creature during world generation then maybe it could be used even if it's not exactly what we want.
