The Truzkul are furred wanderers of the north, descendants of the ancient Trezkul of the more southern forests. They dominate the tundra and taiga, their black skin and black-and-white fur keeping them warm in the cold ranges of the planet. Shown here in a winter coat, they developed these black patches and black skin to absorb the heat of the sun more easily and further improve their warming abilities. Furthermore, the top of their wing is covered in a thick layer of fur, completely disabling flight in the wintertime. The underside remains furless and is purely skin, allowing the Truzkul to vent heat by lifting their wings upwards and exposing the blood-filled vessels of their wings to the cold air around them. The only non-warming marking on their body is the black eye patch that helps reduce the effects of the sunlight's harsh reflections off of their snowy homeland and silvery fur. The fur on their paws greatly increases their surface area, along with the vestigial webs in their digits remaining from their aquatic ancestry. This surface area helps them tread on top of snow, even freshly fallen, and provides traction on the icy shores. Their forepaws do have thumbs, but they are rather hidden in fur.

Living only in family clans and packs, the Truzkul are not as sophisticated as other species of Threa. However, they are capable of the same intelligence and should not be underestimated. Their harsh environment has forced them to be resourceful and clever. Unfortunately, their harsh environment has also made them vulnerable; their fur and skin layout provides the issue of protection compared to other species and they are very small compared to other species in an attempt to conserve resources.

Only males possess such large antlers; females have smaller ones with a few nubs on the edges. Males shed these antlers every year to grow more elaborate ones the next, eventually causing the head to become rather heavy to hold up. The oldest Truzkul prefer to stunt their own horns to relax the strain on their neck.

Truzkul are believed to be opportunistic omnivores. Their jaws are short, but strong, and can latch onto prey with an iron grip. The rear of their mouths also possess very small molars for chewing. Despite their mammalian look, they do not produce milk and have no teats.

Not many civilized Kul have ever met a Truzkul in person. They much prefer to keep to themselves and their cold north. Only during the summer can they dare venture south in their lighter coats, but even then they could easily perish of heat exhaustion in the jungles and deserts of the south. Even the forest can prove too harsh to some individuals.

Speculate as you wish. ;)

Credits to :devsilverdragon4198: for the original Truzkul, basically. Her sona's a big inspiration to these guys' designs and while I would love to take credit for myself, she deserves most of it for the basic look. :) Thanks to her for letting me and Draa create something more from her character!

(I hate shading fur, omg)
