"But will we be able to safely escape here with it?" An advance party had already entered the supply depot. You decided to join them inside the supply depot to look for Drakana. After defeating Balaur lookouts, you made it to the innermost storage space of the depot, where a scout who escaped with the Drakana was found. Though you had accomplished your objective, the depot was crawling with Balaur, leaving no guarantee of a safe escape. The scout used Drakana to craft a handful of explosives. The Balaur were taken out with the explosives, but the scout was injured in the process.
