Planet X

Planet X is a planet in Ultima II. It is where Father Antos can be found. Castle Barataria and Mary's Town are found on it as well.

In New San Antonio, to get the Force Field Ring, the Stranger had to get the blessing of Father Antos, before the old man would sell it to him/her. Using a space ship in the time of Aftermath, the Stranger warped to Planet X, getting the blessing from Father Antos in Castle Barataria to recieve the ring.
