A Friday voyage is a night aboard with the whole crew: fifty pirates on the same instance, on the same deck, in the same hats. Some of us are in full roleplay with a backstory and a grudge. Some of us just came to sing. Both are pirates, and both are welcome.
There is no exam at the gangplank and nobody checks your rigging. Turn up, find a spot at the rail, and let the crew sweep you along. By the second hour you will be calling the floor a deck. By the third you will not remember it was ever called anything else.
