@Grec@PathfinderThank you Path for bringing up the picture part, I was going to ask something about that as well. I can most likely find a picture for the species of the underground but most likely not for the last kin one. Sledge, his name in my Lore that I can easily change for this RP and bring up the nickname later on in a more modern time, is a stranger creature then most people. So if I can have help looking for a picture close to a rough idea of what he looks like would help big time. I'll look still.
General and compact look: Reptilian dragon like creature, stands as Bipedal on two legs, Main wings on his back that have the capability of a rotational joint in both the base and the mid wing section allowing full movement of said back wings, he also possesses a pair of smaller, arm like wings towards the back but downwards closer to his sides that can act as an extra, smaller pair of arms or smaller wings when needed. The creature stands at an intimidating fifteen feet tall with a powerful setup of a body with a tail that ends with a pair of twin endings, like a split a good few feet before the tail should end. May be incredibly easy to find one, but I just look for the four wing one, I'm picky.
The actual description is far better but this is the general look of what his kin looked like back then, his species were strong and caused terror for many that provoked them. None able to stand against them. But once magic came into play, his kin stood no chance at all.
