Suboden Khan

Suboden Khan is First Khan of the White Scars, Master of the Spearpoint Brotherhood, the rider Jubal is grooming because the Great Khan's body will not last the next hunt. Huron's invasion of Chogoris killed the previous First Khan, Jurga, into a Dreadnought. Suboden took the lance.

He fights from the grav-bike Thunder, a Cawl gift, with Stormtooth under the arm as a First Khan's glaive has been carried for millennia. Armageddon knew him before the home world burned. The War Council knows him now as the man who calls the kurultai.

Chogoris still has a Great Khan. Suboden already does the parts Jubal cannot sit a saddle for. The other Khans do not grudge the succession. The orks on the riverbanks do not get a vote.
