No Viking has ever been able to resist a party and even philosophical pirates are notorious for a spot of yo ho ho and a bottle (or three) of rum.
When their invitations are borne on the waves they set sail.
The party to end all parties. The mother of all parties. The Party for the End of Time.
They drink and fight and rape and pillage and burn with the best of them but in the end what's better than man hugs?
