Wyspy Plugawe with delivery to Ireland

What could be better for a pirate than a holiday in hell?
After the war between the angels and the demons, Captain Roland, known as Wywijas, thought he would finally get some rest. Instead, thanks to a contract signed in blood with the devils, he finds himself in command of the naval and land-based sabotage forces of the first submarine in the history of the Wyspy Rozpustne, harnessed to an octopus. Roland only has to persuade his old crew to board this infernal machine. As it turns out, it won't be that easy. The question remains: what are the devils hoping to achieve in all this? Could it be that now they want to seize and take control of the world?
