Tide of Retribution
When the sahuagin named Selachai's parents were killed in a raid against the village of Palma Flora, Selachai made a pact with Uk'otoa and was granted a Rod of Retribution by the leviathan. Using the rod as a focus, she conducted a ritual in 835 PD to sink Flora Isle beneath the waves into Sharkfeather Abyss. The pirate Three Earrings, who was present on the island when it sank, convinced a group of adventurers to defeat Selachai and claim the rod in order to prevent the sahuagin warlock from wreaking more havoc.
