The frost wyvern, Gul'Trekis Qeelak'Marfedelom.
Standing toweringly at Nine feet three inches and near thrice that in length, this giant blue and white Wyvern stands hunched over on two legs and two massive strong wings.
Obviously female, her body is covered mostly of thick hide with strong scales elsewhere on its body but most noticeable on the head and limbs. Four fours that curl along its thick arrow like head that ends with a point on chin & crown leading to a back full of strong sharp scales along its spine and strong flexible tail.
While mostly adept at air combat this creature is strong enough on two legs to easily rip a full grown oak tree from the ground with little issue, be it smashing into it or blasting it with an icy breath that might as well be the lowest pits of the nine hells.
How old this creature is... that is unknown, as the frost Wyverns are always nearly hidden, or trapped deep in icy tombs, sleeping until angered or hungry.
