From the back cover: Abyss is a roleplaying game set in the fantastic world of Dante's Inferno. It is a world of treachery and evil, where violence is a continual threat and doing a good deed could get you killed. Powerful Archfiends dominate a world filled with the lost and the damned, but are themselves dominated by the Lords of the Inferno. It is a world where absolute evil is mirrored by absolute good. Even the Lords of the Abyss must heed the servants of the Divine, or face the Wrath of God and his sword, the Host.
