Sinking of Skull Island

Geological / environmental event

The dormant volcano of Skull Island exhibits tremors over the course of the month. During htis time, the Slavelords capature and deposit the The Loser's Club into an abandoned cave structure on Skull Island. As they try to find their way out, the tremors become more common and the slaver fleet starts to abandon the island.

The command structure of the Slavers of the Yellow Sails starts to fall apart as ships refuse to return to the dying island. The The Loser's Club escapes the dungeon and takes their fight to the Slavelords at the Skull Island docks.

With the Slavelords defeated, and Skull Island sunk beneath the Tentarias, the Slavers of the Yellow Sails disband and the slaving raids abate.
