It's the part of the underworld where legendary figures and the best people are allowed to enter. Given there's no such thing as heaven in that mythology.

Currently at chapter 31, the novel seems to be truly good. The school bits are great and even though I would like a bit more interaction between the characters Infully understand why there isn't. The teachers are great. As of right now with teachers such as professor Messen and Pompei just enough information is given to somewhat understand them while still having plenty of mystery and guessing. Thus far the combat is exciting but a true magical duel has yet to happen, lookong at how the story is progressing though it shouldn't be too far off. The pacing is probably the best part of the novelm Even though a bunch of new things keep getting introduced, nothing seems rushed. Everything seems to make sense as well. I hope at some point we will be able to see the Mortal world amd have some info on that front. Great job thus far author
