Grump and Garland Franks are Fell Tarmick's lieutenants and third in command of the Green Tree Bandits after Faerin.

Grump Berger is a dwarf and the weaponsmith of the gang. He was captured by Borthain during Lost City of Barakus, Episode 26. Although he was likely taken back to Rushbury Mound to face Pohjolan justice, it is doubtful he is still alive.
