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.

Personality
Quite charming and hardworking, however elusive. Not fond of interacting with strangers as much, or giving away information unless he respects the individual, or needs them for something.

"In Love and War" (2x57)
Essek was 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 custody. Before the Bright Queen dismissed the Mighty Nein, Essek was assigned to be their steward while they were potential allies to the Dynasty. Afterwards, Essek took the Nein through the Shadowshire to the Dungeon of Penance where Nott and Yeza reunited. Though coy at first, he did agree to release Yeza after a small interrogation and then continued to show the group around Rosohna, to the Dim's Inn and their new lodgings.

"Agreements" (2x61)
Essek returned to the Nein to show them to their new home, courtesy of the Bright Queen.

"Domestic Respite" (2x62)
Essek dropped by the Xhorhaus, and after Caleb displayed his magical prowess he decided to begin teaching him the basics of Dunamancy.

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