Aurochs

The aurochs are grand oxen creatures of great strength.
This large, horned bull has a dirty black hide and an aggressive temper. Its horns are wide and sharp.

Bahgtru, son of Gruumsh and Luthic, is the orc deity of unbridled strength. Legend says Bahgtru needed a mount as fierce as him for making war, so he sought a mighty aurochs, subjugated the creature with his bare hands, and hauled it to Nishrek, Gruumsh’s realm. Bahgtru named the beast Kazaht, or “Bull” in Orc. On Kazaht’s bare back, Bahgtru charges into battle, ramming into an enemy host and leaping over the aurochs’s horns to land in the midst of his foes.

No orc will eat such creatures, which are treated as honored warriors when they perish.
