Battle of the Celestial Gates

The description that is shown at the start should be placed in some kind of quest as information, so it doesn't get lost after the messages are displayed; otherwise, after a week of gameplay, you won't remember everything.

I understand that the mentor will be in charge of two heroes here, and the map is small for 7 players, so there's nowhere to level up.

Some pretty strong demon appeared as early as the second week of the game https://c2n.me/48fftaj (stats from the tavern are 24-24-40-30). Even though my Frieda is already level 14, and Zephyr is level 11, if he attacks, it's game over.
