The Lost Mine of Phandelver
The irreformable goblin-wife of Gerbo Dargle.
Cleptomaniac, compulsive liar, and unbearably cruel. Also, dead.
Took advantage of Gerbo’s kindhearted generosity, then abandoned him as soon as she realized she was with child. She weaseled her way into the Cragmaw where she raised Gnerx as a goblin. She was killed in a meaningless quarrel shortly after Gnerx turned 3 and became an adult.
