She is a mess of floof. Some might look at her and think she's some kind of a fairy, which is how she earned the name Pixie. She looks like a fairy moth, but as far as she knows, she's just a moth. Her antennae are somewhat feathered, and droop slightly even when held up. Pixie is entirely a creamy white colour, her wings coated in a light dusting of fuzz, and she has a thick collar of fur.
(She is based on the Chinese silkworm moth.)
Pixie was part of an Other-egg smuggling ring in Pyxis, and was smuggled away from the smugglers by a part-blood named Diego. When she hatched, he is the one that took care of her, along with a handful of varying Others, all rescued from the same ring. Pixie's the quiet one, and tends to be the calm older sister figure; Opal's more of the younger sister, given her cheer.
While their time with Diego's never been easy by any means, he's made it as pleasant as possible for them, and has certainly earned their friendship at the very least, though he's also got their loyalty. Pixie's glad he's away from his last handler, but this new one is... well, she doesn't know if she trusts him, but it turns out she's not the only one that feels that way.
They'll see. In the meantime, Pixie's spending a lot of time in the medical bay of Suyis' tower in Pyxis, because Diego almost died, and all the Others he hangs around are just glad he didn't die. Suyis doesn't seem to mind. But of course he doesn't. He's an Other too, and probably understands better than most.
