The Chaos Sanctuary


 * for the actual in-game location see Chaos Sanctuary

The Chaos Sanctuary was what Blizzard called it's battle.net section for Diablo II at http://www.battle.net/diablo2/ starting in August 2000.

Chaos Sanctum was an alternative title for it, as that was the filename used for the banner graphic.

It was eventually closed and replaced with The Arreat Summit, similarly named after the Arreat Summit game location.
