The Eternal Desolate Scorched Hell.
This was a plane without mercy, tolerance, or compassion.
It was the Furnace of Perdition, a four-layered volcano.
In the Scorched Hell, a group of volcanoes with no end and no peak floated in the inconceivable infinite void. Moreover, every level of the Scorched Hell had a central volcano that was the dominant level, connecting hundreds of millions of volcanoes to form the endless Hell Mountain Range. Besides the volcano at the center, the other volcanoes moved in a unique pattern, floating in the void.
In the Scorching Hell, all the volcanoes that could support living creatures were extremely steep and dangerous. They had an inclination of at least 45 degrees.
Demons, Devils, Fumi Ants, Githyanki, Spirit Flayers, Vampires.......... Many creatures from the lower planes lived on the steep slopes of the Scorched Hell. They built castles, fortresses, caves, and other buildings as their homes.
