Avernus was an ancient name for a crater near Cumae (Cuma), Italy, in the Region of Campania west of Naples. It is approximately 3.2 kilometres (2.0 mi) in circumference. Within the crater is Lake Avernus (Lago d'Averno).
Avernus was believed to be the entrance to the underworld, and is portrayed as such in the Aeneid of Virgil. The name comes from the Greek word άορνος, meaning "without birds", because according to tradition, all birds flying over the lake were destined to fall dead. This was likely due to the toxic fumes that mouths of the crater gave off into the atmosphere. In later times, the word was simply an alternate name for the underworld. On the shores of the lake is the grotto of the Cumaean Sybil and the entrance to a long tunnel (Grotta di Cocceio, ca. 800 metres (2,600 ft)) leading toward Cumae, where her sanctuary was located. There are also the remains of temples to Apollo and Jupiter. During the civil war between Octavian and Antony, Agrippa tried to turn the lake into a military port, the Portus Julius. A waterway was dug from Lake Lucrino to Avernus to this end. The port's remains may still be seen under the lake's surface.
In the Dungeons & Dragons fantasy role-playing game, Baator, also known as the Nine Hells of Baator or the Nine Hells, is a lawful evil–aligned plane of existence. It is one of a number of alignment-based Outer Planes that form part of the standard Dungeons & Dragons (D&D) cosmology, used in the Planescape, Greyhawk, and some editions of the Forgotten Realms campaign settings. It also exists as one of a number of faith-based Outer Planes that form part of the separate 3rd-Edition Forgotten Realms cosmology, used in the setting of the same name.
Baator is stylised as a plane of sinister evil and cruelty. The different types of devils that dwell here obey a strict hierarchical caste-like social structure. Each continually plots to advance their position through treachery and deception. Unlike the demons of the Abyss, the devils are highly organized, with a logical and calculating nature.
The plane itself is composed of nine different layers, each of which models a differing but no less inhospitable and dreadful environment, including barren plains of ash and rock to frozen wastes of endless ice.
