Staravosk was the Urgal name for a battle that took place between the Broddring Empire and Urgal warriors led by Nar Tulkhqa in The Spine.
The Imperial soldiers were baited into a tight mountain pass by the cunning Urgal Warchief and then converged upon by Urgals led by many rams. The battle ended in a massacre for the Imperials and the Imperial Army would see its ranks reduced by half by the slaughter's end. It was said later that coins and pieces of armor could still be found in the grounds in that part of The Spine.
Eragon was told this story by Nar Garzhvog when they were at a campfire with other Rams, Angela and several Werecats.
