Aetherian Archive

Craglorn · base game

A tower in southeastern Craglorn, close to the city of Elinhir, holding knowledge the Mage once guarded. Groups fight upward through its floors, clearing atronachs and a wispmother before reaching the corrupted Mage herself at the top.

Bosses4

  • A storm atronach, and the first thing the Aetherian Archive puts in a group's way.

  • The Archive's second boss, a stone atronach grown far past the usual size and cut with old Nedic carvings.

  • A wispmother, and the third boss of the Aetherian Archive.

  • The Mage Constellation given a body, appearing as a masked sorceress the Firstmages called the Learned One. The Serpent corrupted her Apex Stone to force her into physical form, and she waits at the top of the Aetherian Archive.
