Though Doisac is much more tropical than Earth, there are still colder regions, thus clans that have adopted to these regions. Colloquially referred to as "Ice Brutes", "Yetis", and "Barbaribrutes", this clan differs little in physical appearance from other clans, but they are much more adept for colder climates. This has resulted in a more reserved, colder savagery not seen in clans from more tropical areas.

Here you can see the markings allowed to minors, majors, and chieftains respectively.

The only known Brute from this clan to ascend the Covenant hierarchy is Tartarus. Though this is disputed, as he is of mixed clan ancestry.

They have been known to bring larger members of their clan into battle on occassion, usually releasing them from their shackles as a self-destructive last resort.
