Officially? Don't think so.
Egh... odopi, probably a few Tarterian dragons, bonespears, shrieking terrors, varrangoins have been found there, though they aren't native... local hordlings... utukku, vorr... I'd expect some bloodthorn.- I know that vaaths, vargouilles and demodands can be encountered on Colothys. What other natives dwell there?
Me. A more comprehensive answer will have to wait.
