Hahaha, good. We don't actually know if there is or not. We never explored it. The lore might be slightly different, but there's no reason that the name Lazarus wouldn't exist I don't think. Jesu Cristo and Judas Iscariot existed for example :P

They both actually would've played a part in Essence of the World: Tears do Fall, aka Essence S2-A. Idk, I wouldn't worry about it too much.
