She is the wife of Seler Favelnim and part of the quest Bar Brawl. The Nerevarine is tasked with checking in on Seler Favelnim to find out why he's brawling with everyone who comes in contact with him. Dralora will plead to the Nerevarine to not hurt her husband, if he tries to fight back.
The Nerevarine will receive a quest from either Falco Galenus or Carnius Magius, where they will learn that Seler Favelnim has gone on a rampage inside the Raven Rock bar. They will therefore send them to either persuade Seler to stop stirring up trouble or to kill him, depending on the Nerevarine's choice.
