He is bloody red hues with pale leaf-green eyes, a shade darker than his sister, with bits of bone and leaves braided into his mane and a black paint upon his face. The paint also coats the mane around his throat and face.
While his sister is silly and flightly, Okal is serious, if slightly comically so.
Okal is one of the two red lyons hiding in the labyrinthine caverns underneath the Black Mountains. When Zufan tricks and torments Himarta by making the other think she crushed his legs with her magic, he demands she let up and let him go.
As Zufan's brother, it is likely Okal can do magic as well. What this magic is, or if it has been unlocked yet, is unknown.
