Ocean

An Wikipedia:Ocean is yer pirate world. There are four oceans, each distinct an' separate. Here they are:

Midnight is rather an 'old' ocean, and it is quite established already. Ice is the oldest ocean still playable, though it gets reset quite often. It is a test ocean which requires a separate client to play, and so it is ignored by the vast majority of Pirates. Cobalt is a newish ocean, only a while into getting 'set up.' It is greatly similar to Viridian. Azure was the first Puzzle Pirates ocean, and it is now closed.

Viridian is a lot like Cobalt, and was made at the same time. It, however, is the only Doubloon ocean, a pay-for-money-type design rather than the flat-fee subscriber option.
