An entry in the Tenfootpole WaveStone Keep adventure design contest! From the publishers blurb: A fearsome tower of stone prowls the salt-drenched coast! It appears at dusk to disgorge hundreds of rapacious lizardmen who carry off treasure and captives never to be seen again. By dawn, the tower is gone. Deliver the coastline from the terror of the tower! Earn a barony through your bravery or see the coast descend into poverty and piracy because of your failure!
