Ccoa are tiny shape-changing beings that manifest from dark storm clouds that roam the lofty peaks marking the sacred rifts through which mortals attempt to cross into the spirit kingdoms. When confronting mortals, these dark clouds coalesce into small, feline creatures. Slightly larger than a cat but more bestial in appearance, the ccoa is covered with a thick coat of coarse gray fur streaked with black stripes that run the length of its torso. Eerily, its eyes glow with a soft green phosphorescence and its long jaws grimace with rows of broad pointed teeth or less frequently, small tusks.
