The Sunken Temple

From the introduction: A powerful priestess of the sea goddess once lived in a temple off the coast. When an invading force sought to sack the temple and steal the goddesses’ offerings, the sea goddess made the sea rise, drowning the intruders and swallowing the temple beneath the sea. Now, after an age has passed, the barnacle encrusted ruins have resurfaced from the roiling depths. The island now stands as a small cluster of rocks rising from the sea.
