The Greek underworld was made up of various realms believed to lie beneath the earth or at its farthest reaches.

This includes:

The great pit of Tartarus, originally the exclusive prison of the old Titan gods, it later came to be the dungeon home of damned souls.
The land of the dead ruled by the god Hades, which is variously called the house or domain of Hades (domos Aidaou), Hades, Erebus, the Asphodel Meadows (where the neutral souls are sent), Stygia and Acheron.
The Isles of the Blessed or Elysian Fields ruled by Cronus (According to Pindar in his descriptions), where the great heroes of myth resided after death.
The Elysian Fields ruled by Rhadamanthys, where the virtuous dead and initiates in the ancient Mysteries were sent to dwell.

The five rivers of Hades are Acheron (the river of sorrow), Cocytus (the river of lamentation), Phlegethon (the river of fire), Lethe (the river of forgetfulness) and Styx (the river of hate), which forms the boundary between upper and lower worlds.

The ancient Greek concept of the underworld evolved considerably over time.

Hades was not exclusively a realm of torment. This is just more xtian garbage for their bastardized religion of terror.
