Adeen Tasithar

 is a drow male, formerly the Taskhand for the Bright Queen's court. As an NPC, is played by Matthew Mercer.

Appearance
When Fjord talked to him in the Dungeon of Penance, he was bloody and beaten, with one eye swollen nearly shut and his hair tattered and matted. He wore tattered, ragged Rosohna-style clothing, very costly at one point but now torn and dirtied.

Adeen was allegedly captured in the Ghostlands while fleeing the city of Rosohna after the defeat of Obann and the disappearance of Vence Nuthaleus. While he had confessed to giving two Luxon Beacons to the Dwendalian Empire and being involved in the Angel of Irons Cult, he was terribly confused, saying that he had done these things, but he didn't remember how or why. He recognized Vence (being impersonated by Fjord), but didn't know how. He said he felt as if he were going crazy, and knocked himself out banging his head against the wall. The party was convinced he was the victim of some form of mind control, but was unclear as to who had done it to him, and how.

On the night of the party before the Mighty Nein set sail to the peace talks between the Dwendalian Empire and the Kryn Dynasty, the Nein prompt Essek Thelyss to confess that it was he who gave the two beacons to the Empire, in return for their promise to share their research and knowledge with him. This reveals that Adeen was actually innocent and that he had been framed for stealing the beacons. It is likely that Essek may have modified his memory to make Adeen believe he was in he Angel of Irons Cult and that he had stolen the beacons, in order to fake his confession to the Dynasy.

From a distance, the Mighty Nein observed the exchange of the prisoner Adeen for Vence Nuthaleus from the Dwendalian Empire.

Essek Thelyss
While watching the prisoner exchange of Adeen and Vence, Essek states that he had known Adeen "for a while." Their specific relationship is unknown, but when Jester asks him, "Does he suck?", Essek replies with "That is a word, yes." See High Seas, High Stakes
