More Tribe of Shadows lore. Took me about half an hour to think this stuff up.

ABERRATIONS:

Ferus has all the beasts of many Arks. In other words, quite a few, namely Tyrants (Tyrannosaurs and Carchardodontosaurus), Butchers (Allosaurus and Carnotaurus), Trade-beasts, (Galliminus and Paralophasaurus), Winged Horrors (Wyverns and Argentavis), and more than a few others.

But there are also Aberrations.

Aberrations are creations wildly mutated by Element, primarily found in the lost city of Dorban, where the rivers glow at night. One major form of Aberration are the Basilium, a believed-sapient, tool-using race who DESPISE humanity, having raided many cities across Ferus, always retreating back to…wherever they live, it is currently unknown. Their frames are somewhat reptilian in appearance, specifically rather similar to bipedal Managarmr, though with no integration of Holy Tek into their bodies, and they are roughly 9 feet tall with rather jagged crests curving back from their heads. The Basilium wield primitive spears tipped with stolen iron or bronze, or even the teeth of beasts, and extremely simplistic bows merely made of debarked, curved sticks and pieces of stretched Tyrant tendon, though, due to the bows’ size, they are still quite powerful. The Basilium are known to be pursuit predators, or at least assumed to be due to their physiology. Another breed of Aberration is the Teyran Hellrunner, a strange mix of the Allosaurus and Deinonychus, inheriting the ferociousness, strength, and general frame of the first, and the intelligence, large group behavior, and feathering of the latter. Yet another is the Northern Crownstalker, an unnatural combination of the Rock Drake and Yutyrannus. They retain the ground-based mobility and thick feathering of the Yutyrannus, and its commanding nature, while keeping the Rock Drake’s natural stealth and adaptability. The Crownstalkers viciously hunt Basilium, whose common name translates to Crowns, and this earns them the name.
