The official GemStone IV encyclopedia.
Greth Rottgut is the proprietor of the Stumbling Pebble Bar II in Mist Harbor. He is generally an automated Non-Player Character, but has on occasion appeared as a GameMaster NPC in multiple storylines and also at Windfellow's Retreat, where he held a raffle for an unlimited keg of a new liquor he'd developed.
A large individual, Greth has the distinct look of a powerful man gone somewhat soft as the years have passed. Smile lines have sprouted around his hazel eyes, and his bald head shines in the torchlight.
