Background
A number of years ago a druid adventurer was attacked by a small troop of goblins in the woods. In his dying breath, the druid inflicted a curse on the goblin who ended his life. After a few days, the curse began to show itself: large goiter like boils began to grow all over his body and thick mucus-like bile pooled in his throat. The goblin, now estranged from his tribe, suffered alone as the curse warped his form into that of a bloated and grotesque creature.
After some time this goblin came upon another tribe of goblins. These new goblins attacked him upon seeing his horrifying form. The cursed goblin suddenly vomited acidic bile on one of his attackers, killing it instantly. The other creatures stopped their assault and revered the cursed one as being blessed with a divine gift from their god.
They deemed the cursed one: Boilgut, and he became their leader and king.
