Rod of the Callieach

The Rod of the Callieach was a legendary artifact created by the Callieach during the height of their existence. Powered by a Callieach Heartstone, the Rod contained immense power, and an elaborate ritual was necessary for the user to attune to it. Once they do, the wielder becomes impervious to damage. During the Wind Age, Moagim Reborn managed to obtain the Rod for himself, becoming invincible. In the summer of 1435 A.E., Sardonac led an assault against him, and the Avatara sacrificed himself to destroy the Rod, rendering the Faceless Terror mortal.
