Seas of Blood

You are an intrepid pirate captain, commanding the corsair crew of the dread vessel the Banshee through the shipping lanes of Khul's so-called Inland Sea on an avaricious quest: to amass a hold full of lucre through treasure-hunting and outright plunder, transporting it safely through the troubled waters from wretched Tak in the north to the distant southern isle of Nippur.
