Hello again, if it isn’t too much trouble, could I ask what color Halvery and Treace are? I know Arcove is black and Roup is gold but for the other cats I’m a little fuzzy on the colors.
Treace is light tan. He's the same color as Teek. Halvery is dark brown and has black points. That's pretty much all it says in the text of the novel, so you could just run with that however you like.
If you want to know what Halvery looks like in my head - his points are a mountain lion pattern, with a black saddle over his nose and face. He did have a black tail-tip before he lost it (Coden snipped off about a third of his tail). His paws are black, but it's mostly just his toes, not a full sock. Incidentally, he shares blood with Nadine, Arcove's alpha den mother. Nadine and Halvery have a similar color pattern. This is a minor plot point in Arcove's Bright Side.
Correction: Halvery lost more like 2/3's of his tail. I think I say somewhere that it's more than half. He lost enough to make him look strange to other creasia. He got a lot grief about it for a while, especially since cats attach a certain amount of superstitious significance to tails.
