Heroic: Archivum Data Disc and its Normal mode equivalent: Archivum Data Disc start the quest chain required for access to Algalon the Observer. It follows the vein of the Malygos attunement, where only one player in the raid needs the key to gain access to the boss.

The item that starts this quest requires the completion of the Assembly of Iron encounter by defeating Runemaster Molgeim or Steelbreaker last (Medium difficulty and Hard mode, respectively).


Bring the Archivum Data Disc to the Archivum Console in Ulduar.


This platinum disc is surprisingly symmetrical and devoid of any scratches or imperfections. Engraved along it's edge, bold runes spell out the word "ARCHIVUM."

There must be a device inside Ulduar capable of reading the disc.


You will receive: 22Gold 20Silver
