Mistborn shelter was present near the Monkline mountains. It was a purple stage shelter in a cave behind a waterfall that hid it perfectly.
A space broke apart and a figure was thrown out of it.
The force of ejection from the rift was light so he landed perfectly on the ground.
The floor was similar to the ascended platform at the teleporter tower.
Black Stone walls were implanted with magic stones which chased away the darkness.
There were two asuras standing nearby talking to each other. When Rio arrived from the space rift they just glanced at him for a second and continued their talk. They appeared to be in charge of guarding the room.
Rio hurriedly walked out of there as he wanted to go to his destination without wasting time.
Outside of the room had a narrow corridor that was three-way out.
He didn't think much and took the middle one.
