((Aidan and K'Warra are both similar. They have a humanoid face with heavy, 'stubbed' brows. K'Warra also has a pronged chin. Rwos on the other hand has a beaked face and thus doesn't look very human. [Reason: he's from a 'purer' gargoyle strain that hasn't interbred with humans, although he was raised by humans.] All three body types are pretty much the same, except Rwos is brown, Aidan is blue and K'Warra is pale blue-green.
So Aidan and K'Warra look like the same species, but Orthos might not make the connection to Rwos
Will post later, Christmas calls
