Essek Thelyss

 is a drow mage and a senior figure in the Kryn Dynasty. As an NPC, is played by Matthew Mercer.

Appearance
Essek is a very handsome male drow who holds his head high. He wears an elaborate mantle with deep purple and black robes that go entirely around it and fall to completely obfuscate his body.

In Love and War
Essek was among those in attendance when The Mighty Nein received an audience with the Bright Queen, and returned the Beacon to Xhorhas. When Nott inquired about her husband Yeza's whereabouts, it was Essek as Shadowhand who confirmed that Yeza was in fact in their Dungeon of Penance. Before the Bright Queen dismissed the Mighty Nein, Essek was assigned to be their steward while they were potential allies to the Dynasty. He guided them around Rhosona and showed them around the Firmaments.

Abilities
Self-proclaimed time magic specialty, as well as a "prodigy" of dunamancy.
