Pirates Harbour

Pirates Harbour is a city on Earth in the alternate timeline created by Minax in Ultima II. It is located in northern Russia of 2112 A.D. Aftermath, and is the last city on Earth after the nuclear holocaust of a year prior. Rocket ships necessary to travel to Planet X can be found there, guarded by hordes of fanatical communists, who won't hesitate to kill someone they see as an intruder.

When the Stranger returned the timeline to normal, Pirates Harbour vanished as well.
