Universe I (Jenny Everywhere and the Lord of Hell)
From Jenny Everywhere Wiki
In one universe, Jenny Everywhere was a world-class chess-player. Another Jenny briefly shifted into this universe while trying to defeat Lord Grallyx, taking him along with her so as to retcon him into the fabric of that universe. The two ended up playing a game for Jenny's soul until Jenny shifted them again. (PROSE: Jenny Everywhere and the Lord of Hell)
