Phantasy Star I Windows game

Set in Algol, a solar system consisting of three planets. There is the lush and green Palma, the arid and barren Motavia, and finally, the icy and desolate Dezoris. As the story begins, Algol is ruled by King Lassic, who while originally benevolent, becomes a cruel dictator after converting to a new religion. After a string of harsh political changes, small pockets of rebellion emerge, but are mostly ineffective against Lassic's iron rule. When Nero, the leader of one such rebellion, is killed by Lassic's robot-cops, his sister Alis swears revenge. As she travels and witnesses the many victims of Lassic's oppression, Alis' objective becomes less about revenge and more about liberation for the people of Algol. Joined by Myau, a talking cat, Odin, once a member of Nero's rebellion, and the Esper magician Noah, Alis embarks on an adventure spanning all three planets, to eventually engage King Lassic and determine the fate of Algol.
