The Mystery of MM
The oldest of the Gruffs and currently holding the PC's responsible for the murder of one of his younger brothers
From appearance Gruffs look like upright walking goats. They are equally good at killing with modern weapons as with ancient ones. They are smart and are highly ranked in the Summer Court so the death of one is no small matter.
Elder Gruff is the oldest and largest of the 5 Gruff brothers and as such is in charge. He has little patients for human sensibilities, but like all Faeries is bound by the letter of the promises he makes or receives.
