The Order of the Hidden Moon
The Order of the Hidden Moon was an ancient Khajiit order dedicated to Azurah, based in what became the Ashen Scar. They were responsible for dealing with the Dro-m'Athra, by using a form of necromancy which would allow the dark spirits to redeem their corrupted souls and to pass through The Crossing. The Moonlight Blade was the special weapon of their order, blessed by Azurah herself.
