The Obsidian Keep (LL) (2020)

From the publishers blurb:

Last month, a fleet of holy warships sailed out to destroy the evil sorcerers of the Obsidian Keep.

The fleet never returned.

Today there is a call for righteous heroes (or brave treasure hunters) to find the fleet, rescue the sailors, recover lost treasures, and discover the fate of the cruel masters of the Obsidian Keep!
