Sark/Stereotypes
Humans - Humans are, generally, greedy, scared little things that will kill anything they dont understand, so it is ideal to stay away and Dont Poke The Bear. HOWEVER, Sark has been informed that during his long sleep, humanity has largely forgotten that creatures like him exist anymore, so he's chosen to be VERY CAREFUL and start exploring Prospect and all the fascinating changes the little critters have wrought in the last 4 centuries.
Changelings - Sark is more empathetic towards the Nunnehi as he doesn't see them in the same 'invader' light as other changeling kiths, but he barely knows enough about any of them to make better judgement calls. He does know most dont mind his presence, though there are some that will see the scales and immediately consider him a glorious quest to be completed. Better to stay hidden and not push one's luck.
Other bygones - Sark has been hibernating for a very long time and it has been warned to him that others like him have become few and far between along the passage of time. Finding another mythological creature would fascinate him akin to an overenergetic puppy finding a new toy. Maybe not quite that bad, but he'll have trouble containing his interest and fascination.
Mages - These get a separate mental category because to Sark's view, these are humans that learned much more dangerous skills and need to be approached with more caution than the 'average' human.
Other Supernatural Creatures - For the moment, all of these (vampires, werewolves, other shifters, demons, etc) get lumped into the same mental category, because Sark does not know any better about their specific details yet. He is, however, interested in learning!
