Azure Bastion - The Half-sunken Castle

Publisher's blurb: The Azure Bastion was once an important coastal fortress keeping an eye on a narrow passage on a peninsula leading to the properous harbor city of King's Bay. But the great Spellquake changed everything. Landmasses shook and churned in ways never seen before. Islands, even whole continents, sunk in the oceans over night. Mountains were torn from the ground and floated high up to the clouds. Spellquake laid waste to King's Bay as well collapsing most of its buildings and driving people away from their shattered homes. Now the great city is lies in waste. Abandoned and pillaged by savage goblinoids and lizardmen. Pirates and smugglers are the only ones who dare to tread these waters. Finding shelter in the ruins and caves of the archipelagos and swamps that are the only thing that remains of the great peninsula.
