A Two-Round Living Greyhawk Nyrond and Her Environs and Splintered Suns Meta-Regional Adventure
From the introduction:
For months rumors have said that an evil fleet sails the Solnor Ocean, preying on ships of all nations and leaving few survivors. The rumors have now been confirmed, and a storm gathers in the form of an armada of the undead. Can a band of brave adventurers sail to a mysterious location and recover a hidden treasure that might avert the coming tempest?
A two-round Nyrond and her Environs and the Splintered Suns meta-region adventure set on the Solnor Ocean for characters level 4 - 16.
Part 3 of Terrors of the Deep (not for those with a dislike for the ocean).
This module is nearly identical to NMR7-06: Eye of the Tempest.
