Seas of Blood (1985)

Adaption of the Fighting Fantasy gamebook of the same name.

Storyline

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.
