Betrayal in Antara is a Windows 3.1 computer role-playing game developed and published by Sierra On-Line in 1997, after the success of their previous RPG, Betrayal at Krondor. Sierra had lost the rights to produce another game based on Raymond Feist's Midkemia, and therefore had to create the game world of Ramar. Although it is not a sequel, Betrayal in Antara uses an updated version of Betrayal at Krondor's game engine. Source: Wikipedia, "Betrayal in Antara", available under the CC-BY-SA License.
