in fact i have just now decided that his default familiars are 4 crows, a raven named moose, and a ghost named crow
i've been thinking about how casimir met zuzu and how they got together. it's all very vague to me still. i've been focusing so much on his relationship with gareth, because that's when the plot really kicks off, but he was with zuzu for years before that, and zuzu is in fact an extremely plot relevant character even though they're not endgame romance. the breakup frees them to go off and be a roaming plot nexus that shows up when needed. and of course their friendship is forever. i don't even know what zuzu looks like -- but to be fair, neither does zuzu.
yeah, they're like loki -- they don't naturally have a gender really, they're nonbinary and switch from day to day, and also can change their appearance almost effortlessly. the farther from human they look the harder it is, so while they can shapeshift to like orc or merfolk with a bit of sweat, turning into a bird is something that's not worth doing bc it's so exhausting it'd be better to use a spell.
Spoiler: zuzu is... ... secretly the trickster god. they have deliberately forgotten this, not in an amnesia way but in a way where it comes back sometimes and they're like "oh, i was going to not have that in mind lest i give myself away" and shove it back down.
i think the reason they fell for casimir is bc he can always identify them no matter how their appearance changes. and he doesn't treat their shapeshifting as dishonesty or sneakiness, more like a cool puzzle that's fun to solve. he's always so delighted when he realizes it's zuzu he's been talking to. like zuzu is a surprise party just for him.
the kings admiring each other's magical philosophy casimir: most people, when they start looking at the big questions, life and death, why we exist, how big the universe is, they start feeling insignificant, and it freaks them out. they start thinking in corkscrews trying to stay important. but you don't think like that, do you, in terms of important? just interesting. gareth: exactly! you DO understand! casimir: yeah, i get it. it's not where i am but i see how you got there. gareth: no, you learned you weren't important and felt relieved, didn't you. casimir: yeah, pretty much. gareth: everything dies and that's great, right? casimir: now you're making me sound like an edgy teenager. gareth: it's not much work. casimir: (fondly shoves him off his chair)
which is to say... gareth: the glass contains 50% of its capacity casimir: that's not relevant to its being a glass, glasses are always emptying and filling, that's what they're for
