Summoner 2 takes place twenty years after the events of the previous game, where a young woman named Maia becomes the incarnate of the goddess Laharah and the Queen of Halassar. Maia's people worship Laharah as a benevolent creator, unlike her predecessor Joseph's culture which hated her. Maia was born with the mark of prophecy, her fate written in the Book of Prophecy. She knows she must fulfill her destiny, but is unsure of the path ahead.
Summoner 2 introduces a new action-oriented gameplay style, where the player directly controls Maia's physical attacks. The game features a party system, allowing three characters to accompany Maia on her journey at any time. Character abilities and skills can be improved through the story, and players can choose to adventure in "solo-mode" without their party members.
