After walking inside the place, he was immediately met with a burning air on his face but mostly in his sea of consciousness.
There wasn't much to the place besides, a long path and a dimly lit corridor that exuded light due to the heat of the passage.
The burning air grew more stiffly the further one took a step inside the place.
The air grew hotter, but Ainz didn't feel any discomfort in his body, as he inhaled it to help resist the headache he was feeling.
He walked till he was at the end of the corridor, and could see a large circular hall room, with the burning sensation being at the highest almost as if a burning flame was placed inside of the place.
The room just like the corridor was quite simple, it had no doors but only a dark floor that looked like charcoal, the charcoal floor seemed to be what was producing the heat in the room.
