Diablo is the first installment in the Diablo video game series. The player controls a lone hero battling Diablo, the Lord of Terror, in the fictional Kingdom of Khanduras in the mortal realm, traveling beneath Tristram through sixteen randomly generated dungeon levels before entering Hell to face Diablo.

Blizzard North (formerly Condor), which was the Bay Area division of Blizzard Entertainment, created the game. The studio, based in San Mateo, California, was well-known for its Diablo series. On August 1, 2005, Blizzard Entertainment announced the closure of Blizzard North.
