Syra explained a bit about her world and some stories about the past Omni Mages and that there hadn't been one alive for about 2000 years.
She and Shingi discussed the differences in how magic worked, and there were a few fundamental differences.
First, they didn't have a Mana Tree. Syra and the rest of the people from her world had a Mana Pool of different sizes for each person but no Mana Tree, Mana Seeds, or Mana Fruits. Shingi guided her to access her Mana Tree, but she was unsuccessful, like not having one, even if she had a Mana Pool.
Shingi, in all his years playing the game, never encountered something like that. Of course, there were instances of opening on even different dimensions, but they followed the same principle, maybe with a few slight differences. But in Syra's case, there were more than subtle differences.
