"The phantom of Eriana-3 now haunts me alongside the rest. They are a burden that weighs heavy on my mind."

The Cryptoglyph must be used to empower the Lectern of Enchantment near Eris. In tandem with the cleansed Essence of Anguish, this will yield another piece of Dreambane armor.

Empower the Lectern of Enchantment with the Cryptoglyph before setting off to hunt the remaining Nightmares.

More Nightmare Essences are required to craft the remaining three pieces of Dreambane armor.
