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 has very short white hair. He wears an elaborate mantle and deep purple and black robes that almost entirely obscure his body. Under the mantle, he wears comfortable, sleek, well-trimmed Xhorhasian-styled clothing.

Essek moves in a unique way, described as gliding or drifting. His cloak falls to the floor, obscuring his feet. Although in the Mighty Nein's initial meeting with him, they heard and saw his footfalls as he moved, later Jester peeked below his cloak and saw his feet weren't touching the ground. Once, when he came to the Xhorhaus, the party scattered ball bearings on the floor, which separated out around his form like there was some invisible force pushing them outward and generating a strange force keeping them at bay. At Mythburrow, he left two grooves in the snow behind him as he moved, from his toes. At Matthew Mercer's Stockholm Comic Con panel, he clarified that Essek can walk; he simply chooses not to. Later, the party learned that Essek floats because when he was young, he used it as a means of impressing people, and now it has become expected of him.

Personality
Essek is quite charming and hardworking; however, he is elusive. He isn't fond of interacting with strangers much, or giving away information unless he respects the individual or needs them for something. He is arrogant in his abilities. Although he may be concerned about the Mighty Nein, as a person of his training, his station and his general persona and how he likes to present himself, he would never openly show that concern.

Essek has expressed frustration with the Dynasty's religious beliefs concerning the Luxon Beacons and The Luxon. He feels they are based on myth, interpretation, and assumption, and distract from the effort to pursue the power contained in the beacons. His beliefs cut him off from others of the Dynasty; he does not trust anyone and feels like he doesn't belong. Therefore, he spends much of his time alone.

Background
Essek is a member of Den Thelyss, one of the three main important Dens of Rosohna. He is consecuted, but has not gone beyond his first life yet,, and is part way into his second century. He considers that Den Thelyss was very kind to accept one as comparatively young as himself. He holds an apparently high position in the Xhorhasian government, going by the title "Shadowhand", but it is unclear the specifics of his job.

Essek has revealed that he believes the worst thing he's ever done is anger his father to the point where he went unprepared into the depths of Bazzoxan and didn’t return. He believed that his father wasn’t a great man and had little aspirations. His mother, however, is the Umavi of Den Thelyss.

Essek was in attendance when The Mighty Nein received an audience with the Bright Queen, and returned the Beacon to the Kryn Dynasty. 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.

Essek returned to the Nein to show them to their new home, courtesy of Den Thelyss. It is raining, but the raindrops do not touch him, instead falling around him while he remains dry.

Essek dropped by the Xhorhaus and remarked on how the Mighty Nein are settling into their new home. Beau invited him in for drinks, but he declined. After some polite conversation, Caleb asks after ways to learn dunamancy. Essek asked him to demonstrate his magical prowess, and Caleb cast Cat's Ire. Essek then decided to begin teaching him the basics of Dunamancy, offering to let him transcribe two spells from his spellbook.

Essek vouched for the party in their meeting with the Bright Queen sharing information about the upcoming attack on the Ashguard Garrison and the meeting at the Overcrow Apothecary.

Essek was present for the Mighty Nein's audience with the Bright Queen following their return from Bazzoxan and said he could transport the group to the Flotket Alps. When Caleb sought him out afterwards, Essek agreed to do what he could to see that the captured Scourger's execution was not accelerated.

When the Mighty Nein are ready to leave for the Flotket Alps, they send to Essek to come to the Xhorhaus, where they introduce Dairon as their house sitter. After one unsuccessful attempt, Essek successfully transports them all to the Greying Wildlands.

The Mighty Nein sends to Essek asking him to Teleport the party to Mythburrow and he agrees. When they return to Rosohna, he also helps Caleb by using Dispel Magic on the stolen book page, unlocking its contents, and tells Caleb he has been able to delay the execution of the Scourger for two weeks. Reani finds him very attractive and is overawed and shy around him. Essek then successfully Teleports all of them to Mythburrow.

When Essek moves away, Jester sees that instead of footprints, he leaves two grooves in the snow from his toes dragging through the snow.

Essek escorts the party to the Dungeon of Penance to interrogate the captive Scourger, and when she attacks Caleb, Essek uses magic to lift her still-living body off the ground and magically crush her central torso inward, killing her instantly and mangling the body. Essek later teaches Caleb two new dunamancy spells, Immovable Object and Resonant Echo.

Essek transports the party to the Lotusden Greenwood, but there is confusion over their intended target and they then ask him to teleport them further south in an attempt to intercept or get ahead of Obann. He is extremely reluctant. When Caleb places his hand on his forearm and apologizes, he pulls away. However, Essek agrees and teleports the party deeper into the forest. When Beau asks if he's mad at them, he says he is just ready to leave, reiterates that he has not forgotten that the party now owes him a number of favors, and tells them to be careful and safe. He exits by casting a spell that sends him flying up through the canopy.

The party returns to Rosohna and meets with a weary-looking Essek, who tells them of the captured Adeen Tasithar, and that Adeen has been being interrogated for two days. Essek agrees to taking a disguised Fjord into the prison to see if he can learn anything further. When the party tells Essek they think Adeen was mind-controlled, Essek goes to check if he has a mark on his neck similar to Yasha's. He is Insight-checked on his return by Nott, who later tells Caleb that Essek seemed "funky".

Sam Riegel later revealed that, on that Insight check, Matthew Mercer had whispered that Essek was being weird and was lying about something about the prisoner, and that he was "completely not himself."

In Nicodranas, Caleb discovers Essek secretly meeting aboard a ship of the Cerberus Assembly. The Mighty Nein soon confront Essek, and he confesses that he stole the Luxon Beacons from the Dynasty and for research purposes gave the Beacons to certain members of the Cerberus Assembly (Martinet Ludinus Da'leth and Trent Ikithon, with Vess DeRogna commanding the research), setting off the war. Essek claims that, when the Mighty Nein returned one of those Beacons, he tried to stay close to them to lead them away from the truth, but he grew to care for them. Now that the Assembly has a freshly unearthed Beacon, the conspirators are content to return the remaining stolen Beacon to the Dynasty and continue studying the new one, sharing research via correspondence. Essek claims he and his co-conspirators are trying to ensure that "outside interests" do not disrupt the attempt to return the Beacon and end the war.

Home
Essek lives in a gated community within the Firmaments District of Rosohna. His home consists of three towers of different heights connected by walkways. At the top of one tower is a weather-vane type mechanism that tracks the shifting ley lines. It is built of slightly iridescent grey brick.

Quotations

 * "[The Luxon] is the basis of how we've been able to free ourselves from the binds of the lineage the Betrayer Gods left for us and to carve our own fates, choose our own paths and sidestep these destinies placed upon us nonchalantly by gods that use us as playthings." (Essek explaining the significance of the Luxon to Dunamis power)
 * "Time is one of my specialities." (When asked why he isn't affected by the dunamantic time distortion in the Dungeon of Penance)
