Thanks Steez

Been thinking how I'd have multiple quest from one guy, but it's easy to just have the actual quest's seperately (as they begin by accepting notes and challenges), and just have my npc as an alias, and giving him the skin/heart or whatever of the creature as the quest complete.
Then he can have the dialogue "quest" and it makes it all simplified.
Modding and scripting seems really daunting at first, but it's all logical isn't it. It all makes sense once you learn the functions and stuff.
