"Proceed hero, into Terror's lair. Know that Diablo's innermost sanctum is hidden by five seals. Only by opening each of these five seals, can you clear your way to the final battle." - Hadriel

The Chaos Sanctuary, also referred to as Terror's Lair by Hadriel, is the unholy cathedral of the Lord of Terror himself. Inside the Sanctuary, Diablo is hidden in his innermost sanctum. This sanctum is hidden by five seals which must all be opened in order to reveal Diablo himself. This particular function likely has nothing to do with lore and all to do with game mechanics, forcing the player to defeat three mini-bosses before fighting the original last boss of Diablo II.

Three of the five seals release a Super unique monster with a group of boosted minions. These are:

• The Grand Vizier of Chaos, a Storm Caster
• Lord De Seis, an Oblivion Knight
• The Infector of Souls, a Venom Lord

When all three super uniques are dead and the last seal is opened, all other monster in the sanctuary automatically die as Diablo makes his appearance.
