Reili
So... Why did she need to join the mages guild for the access to that hall again? She literally went there to enter her Mana Realm, but now she does it in a random dungeon? I suppose it might be, first time only. But it's a bit confusing none-the-less, a slight mention about "now that she already reached her mana realm she can attempt it from here" or something would help make it less of a "fridge moment"
