Magpie, another Everpaw cat, died before they even opened their eyes. They are the littermate to twins Crow and Raven, younger siblings of the Everpaw leaders (again twins) Darkpaw and Voidpaw. All five kids are from the same mom, Black hole, but only Crow, Raven, and Magpie are Inky's kids. Void and Dark were Black's first accidental kits.
Magpie loves mischief and spending time near their living family. They occasionally find Black Hole while she wanders the world, still grieving Magpie. They always stick nearby her on their birthday, to watch the star showers that appear every year.
Magpie has no eye color because they don't need eyes as a spirit and never really experienced sight in the first place, so they have no attachment to being sighted or not.
