Merv the Griffin is a griffin that has built a nest outside of Shapeir. It was his feather that the Hero obtained to create dispel potions with Harik Attar. Some of his feathers had shed, including one which ended up underneath a rock. Most, however, littered his nest.
Merv the Griffin is a character and easter egg in Quest for Glory II: Trial by Fire. Though it is possible to fight him, he is the most difficult monster to defeat in the game. His name is a pun from Merv Griffin.
