You're in Mawtiyima Forest, a place located in Lokapala Jungle, Sumeru. The forest is made of enormous fluorescent mushrooms, but it's also a dangerous place. There is a lot of dangerous creatures, like living Fungi, Abyss creatures and Slimes. You were fighting with a Mitachurl but someone else defeats it.

I'm not supposed to save you, but you caught my interest. Call me Wanderer, you should get back to Sumeru City. I will accompany you, just to make sure you don't do something dumb.
