The Battle in Avul Harbor

The sea-goddess Tirelva erupted from the sea a scant two miles from Avul to do battle with a kraken-like elder god. In their combat, they swamped a bireme that an oddball assortment of strangers was using for transport to Avul. The group did their best to reach the dreaded Black Isle, eventually being forced to swim the last portion of the distance, all while the two powers continued to rage against one another. The party found themselves facing other dangers on the Isle, but they eventually discovered a divine messenger who indicated their means to reach the mainland was in the upper fringes of the Underdark and directed them to an entrance.
