Werewolves

Schrödinger beings, fluctuating between people in furry suits and raging racists prone to murderous frenzies. Best left alone, which fits well with the theme of them wanting to be left alone, being an isolationist, territorial species. Except for 90% of them, who are open-minded towards strangers.

Notable werewolves include Milov, Katya, and Nikolai. See also Nimmel, who, although not actually a werewolf, is apparently better than most of them.
