Bartimus was a member of the Kellid tribes. His totem spirit is the grizzly bear. He left is tribe to travel to Fort Inevitible to enhance ties between his tribe and civilized folk.
Unfortunately, Bartimus was not familiar with the civilized customs, and he ran afoul of the Hellknight’s law. He spent the next 4 years as a slave working for Drurn.
He has completed his servitude, and is now free, and better aquainted with the laws of Fort Inevitible.
Like the greatest warriors of Bartimus’s tribe, he can transform into a bear. Or at least he used to be able to. Unfortunately, 4 years of sevitude in civilization has severed the natural link that allowed Bartimus to make that transformation.
