The Samoyed tribal law says: The tribe can be lead only by the strong warrior.
If someone wants to be chieftain of the tribe he must challenge the chieftain to a duel.
So Alconan Dreadeye from wolf clan and Ukene from polar bear clan met together in Vologda. The fight took place near of the saint birch. Ukene gave offering to the saint spirit of the tree. Than they started to fight.

The Spirits choose the youth.

QUOTE:
Ukene won the fight!

From now on Ukene is the Chieftain of Samoyed tribe.
