Lost Mines of Phandelver
King Grol was a fierce old bugbear that ruled the Cragmaws through pure intimidation. Although age had stooped his shoulders, hunched his back and greyed his fur, Grol was still surprisingly agile…and especially strong. This great strength was likely the result of a pair of enchanted gauntlets he wore.
No other Cragmaws dared to cross the demanding and vidictive King Grol, not even the ambitious Klarg (not directly anyway). Grol was always attended by his large pet wolf, Snarl and a pair of hobgoblin guards.
