Kanimir is, as he often is, sitting in his library enjoying a book on magic and pondering theoretical innovation. He has an idea; he writes it down. It probably won't pan out, most of them don't, but it might.
"Vampires are similar to humans but immortal and sustained by blood. And with a few other alterations."
"Oh. No. I wouldn't need to put as much effort into wards if I were very immortal. Elementals are truly immortal?"
"Because I was a vampire, because I was a 'witch,' because I was a threat to my half-siblings' inheritance..."
"Most people these days don't understand that they're real. Most people a few centuries ago did, but knew very little that was accurate and quite a bit that was wrong and abhorrent."
"Do you happen to have a place we could crash at least until Penumbra can move us on?"
"It keeps us alive, but it has--degenerative mental effects over time. From what I can tell the effect is roughly that drinking a creature's blood as a vampire pulls one closer to the creature in mind and body. With humans the effect is utterly negligible. With animals--well. The mind goes first."
"Although now I'm sorta curious what an elemental's blood would do."
"Um," says Penumbra.
"You don't have to try it," Maurabel assures her.
