The sharthak are ocean-dwelling shark-men. They’re carnivorous, feeding mainly on fish and whales but gladly take human prey whenever they can. Sharthak are possessed of a generally selfish and cruel nature, and are greedy, temperamental, and vicious, favoring thrusting and stabbing weapons such as tridents, spears, and daggers, and also use nets to good effect. They fight together well, and prefer to overwhelm their enemies with swarms of warriors. They breathe air as well as water.
The company encountered the sharthak while delivering the Spear of Vergaine to the King of Umbr. At that time, the sharthak possessed the Conch of the Kraken, an artifact which both summons and controls the legendary Lake Beralka Kraken, as well as a magic ship which sails as well beneath the waters as on the surface. The company and the sharthak fought to a draw, and the companions tried to draw the sharthak into an ambush a few days later in the village of Vrazha, Mircaséa.
