|Featured In||The Reckoners|
Nightwielder is a High Epic that is part of Steelheart's inner council. He is the one responsible for Newcago's constant darkness. Nightwielder was killed by David Charleston's exploitation of his weakness during the Reckoners' assassination of Steelheart.  He is thought by David to be of Japanese descent. 
Abilities and Attributes
- He can pass through matter and no weapon can harm him while in this form. Nightwielder is almost never seen in corporeal form.
- Nightwielder is powerful enough to keep the entire city of Newcago dark except for the light from Calamity.
- Dark mist
- Nightwielder exudes a dark mist that pools around him. The mist can be controlled by him and be given solid form, for example, a spear that can impale someone.
- At a few points in Steelheart, Nightwielder displays the ability to levitate and fly. This ability appears to go in tandem with incorporeality. 
Nightwielder becomes corporeal whenever he has UV light shining on him. It has been theorized that this is due to him having had skin cancer at some point before he became an Epic.
