The Crimperio Alliance was one of the largest alliances of 2004 on the Midnight Ocean, during what was often considered to be a particularly polar political environment. The alliance was between two of the largest Midnight powers at the time - Crimson Tide and Imperio, whilst Tyr's Own and The Jolly Company comprised the other founding members. The physical manifestation of the alliance was an alliance web, in which all of the contributing flags were allied to one another, the name "Crimperio" existing in the social sphere of Y!PP only.
