Story
Having completed preparations for infiltration, you crossed to the Balaur base, passed the narrow bridge, and headed into Dranactus Underkeep. Rescue the last Destruction Archon.
After completion (spoilers)
"I... must atone for my sins." Having completed preparations for infiltration, you headed straight for Dranactus Underkeep. Predictably, the area was overrun with Balaur, but Nemon and Menrik didn't show even the slightest hesitation. The Underkeep, reached after passing through the Balaur base and across the narrow bridge, was a hell even worse than Ishalgen. You rescued the emaciated Reuben from the depths of the Underkeep, where he had been tortured, and brought him to Briskwind Shelter. On the verge of death, he expressed his wish to atone for his wrongdoings and asked you to release his apparition in the Impetusium when he died. In exchange, he told you the location of his hideout.
