Poseidon creates the Adveni Sea

Geological / environmental event

When the old gods came back there were lots of changes they wanted to make. When Poseidon learned the mermaids in Avalon Valley had no sea or ocean to swim in he became enraged and created a sea for them to live them.

The Adveni Sea or Adventurer Sea in common, is a large sea that goes from middle Utah through parts of Nevada to California as well as up into parts of Idaho and Oregon. Not only is it abundantly filled with life created by Poseidon and cultists alike but also the home for most Merfolk in Avalon Valley and the Western United States. This sea also provides trade between the Azteca Empire, Avalon Valley, and the Republic of the Rising Sun.
