Quaalus is the resident alchemist in Surdana. He has a menagerie of strange beasts in his laboratory, including shrunken-down scavengers, grulls, and wartoks. Rynn can purchase potions and elixirs from him.
Quaalus is always performing some form of experiments. He asks Rynn to acquire blackwing eggs for him, offering to pay 50 gold a piece for them.
