Umbrakinesis, or Sciakinesis, is the ability to mentally generate and manipulate darkness, the absence of light. One with this ability can even deactivate and repulse or travel through shadows (see Shadow Travel).
Percy Jackson and the Olympians[]
The Battle of the Labyrinth[]
After the battle, Nico walks into the woods and Percy follows him. Nico tells Percy he has to investigate his past. As Nico walks away, Percy states that the shadows of the forest were reaching out to Nico as if they were embracing him.
The Last Olympian[]
Nico shows that he is able to Shadow Travel, the ability to travel through darkness. Most Underworld creatures are also able to do this, as shown by Mrs. O'Leary's ability to do the same.
Hades fires a bolt of "dark energy" at Percy, which the latter deflects. In a flashback, Hades saves Nico and Bianca from being killed by creating a barrier around them right before Zeus obliterates their hotel with the Master Bolt.
The Heroes of Olympus[]
The House of Hades[]
Eris, Geras, and other children of Nyx make the area darker to prove they are the darkest child of Nyx.
