Neptune

Neptune is a planet of the Terran Solar System in Ultima II that can be visited with the rocket ship in the time of the Aftermath. Minax' meddling with the timestream had caused the planet to be quite different from its original state.

There is next to nothing on this planet, apart from the mysterious Computer Camp village.

Neptune is on the space chart of the documentation, and its coordinates are 4,0,5.

Trivia

 * In reality, Neptune is a gas-giant planet with no solid surface. Besides its deadly pressure and atmosphere, it also is freezingly cold.
