In the depths of Hell, there is a species known as the Uoinota Calti; a sort of demonic, hell cat-dragon hybrid.
Although their origin is the deeper, darker depths, different clans/tribes can be found just about anywhere in the realm.
 Tyler's clan of origin, the Plythu Vers, can be found between the Devil's castle, and Hell's gates and act guardians.
                           Although considered weaker on a general basis, once angered, the Plythu Vers are quite fierce.
