I mean, it's the only magic system I know, so I can't say much about that. [Momo shrugs almost apologetically. He's encountered a whole lot of people here who have magic in their own worlds that's distinct from what exists here, but in his case it's just stories and this is the first actual experience he has with it.]

I posted a map with the first message, if you get back to the underground city you should be able to find your way to the tunnel I'm in. And "as soon as possible" would be nice, but I might need a couple of hours to see if I can get some extra help. But I don't mind starting on my own if you want to come back me up.
