Eberron: Scales of War
Brindol alchemist, one of seven prisoners captured by the hobgoblins and held at Rivenroar.
When discovered in a small chamber off the Von Jallach family crypt, the dwarf Adronsius is in bad shape. He has been repeatedly beaten and threatened by his hobgoblin captors, leaving the dwarf extremely bruised and bloody. When the party find him, they patch up his wounds as he tells them how to find another of the kidnapped citizens of Brindol. He offers to accompany the party, but the crone Zerriska is quick to point out that the dwarf is no warrior and is instead a mere alchemist. Adronsius agrees to remain behind with Zerriska and defend the chamber.
