Shadow and Bone
Dubrov traveled into the Fold with Mal, Mikhael, and Alina. He survived the crossing attempt.
Later, he was in the group that was hunting down Morozova's Stag for Alina Starkov. When Mal volunteered to cross the Fjerdan border to retrieve the stag, Mikhael and Dubrov volunteered as well. Mal survived, but Dubrov and Mikhael had been killed by the Fjerdans when his unit tried to escape their borders back to Ravka, along with six other volunteers.
