Nyx, sometimes referred to as "Mother Night", is the personification of night and a resident in the House of Hades. She is the mother of twin gods Hypnos (Sleep) and Thanatos (Death), of Eris (Strife), Nemesis (Retribution), and many others. She is also the caretaker of Zagreus. After Persephone left the Underworld, Nyx became Zagreus' main caretaker. She curried favor with the Olympian Gods and gave Zagreus the Mirror of Night to aid in his escape. She holds a managerial role in the House (leaving bureaucracy and ruler-ship to Hades), and can be seen giving counsel and direction to Megaera, as well as giving orders to and reviewing the day's work with Dusa.

Hades
Hades is a rogue-like dungeon crawler in which you defy the god of the dead as you hack and slash your way out of the Underworld of Greek myth. We think it combines the best aspects of our previous games, including the fast-paced action of Bastion, the rich atmosphere and depth of Transistor, and the character-driven storytelling of Pyre.
