Kingsport - Forgotten Realms
Avatar of Lloth
The true boss fight of The Fang. The Avatar of Lloth was attempting to enter Faerun through a portal opened at the top of The Fang. After consuming Lysa, the Avatar tried to pull the portal open as the party tried to beat it back and close the portal.
Dropped some sweet loot before bringing the place down, damaging the portal device and causing it to rapidly switch between destinations, sending most of the party to The Friendly Arm Inn and Aszuryx to a mystery desert location.
