Lythir VaSuun is a drow mage of the Kryn Dynasty. While leading an ambush against the Muck Men in the Ashkeeper Peaks, Lythir and his war party engaged in battle with the adventuring party known as the Mighty Nein. As an NPC, Lythir is played by Matthew Mercer.




Lythir is a loyal and nationalistic soldier of the Xhorhas Empire. In contrast to the "brave" Kryn soldiers, he sees the Dwendalian Empire as "filthy ilk".[1] Despite the disadvantage in numbers against both the Muck Men and the Mighty Nein, Lythir's use of dunamis to manipulate the battlefield provided a remarkably strong advantage, potentially honed over generations of beacon use.

"Xhorhas" (2x51)[]

Leading a Xhorhasian war band of gnolls, with an echo knight (Kryn warrior) escort, Lythir ambushed the Muck Men along the Ashkeeper Peaks. The Mighty Nein (hidden nearby) decided to enter the fray on the side of the Dwendalian scouts.

Caleb, Nott, and Fjord helped keep Lythir and the gnolls occupied, while Beau, Jester, Caduceus, and Yasha focused their attention on the echo knight on the other side of Caleb's Wall of Fire. Jester and Caduceus' Bless helped the party brave Lythir's Cloudkill and allowing their attacks to get through the Kryn's' high armor classes.

The Muck Men were almost all wiped out by the echo knight's swift blows and Lythir's spells, which altered the reality of the battlefield.

Having taken heavy damage, Lythir and the echo knight retreated. The death toll from the battle was eight Muck Men, five gnolls, and one barlgura (summoned by Fjord with Summon Greater Demon). Although the Nein could still consider it a victory, the ramifications of two powerful Kryn soldiers escaping alive (who knew their descriptions) remained to be seen.

"The Favor" (2x56)[]

Lythir met the Mighty Nein again when they arrived at the Aurora Hold to seek payment from Lady Zethris Olios for dealing with a demonic incursion in Asarius (though the adventuring party failed to recognize the mage without his armor). He inspected the magic items brought by the Nein, confirming their claim to Lady Olios. He then removed a crystal from the Abyssal anchor to permanently deactivate it.

Lythir teleported along with the Mighty Nein to the Cathedral of the Bright Queen. During their audience with Leylas Kryn, Lythir identified the Mighty Nein as the group that had attacked him in the Ashkeeper Peaks, causing the Queen to call for the group's arrest.

"In Love and War" (2x57)[]

Lythir was present during the Mighty Nein's conversation with the Bright Queen about the history of the Luxon beacon. As they were leaving the chamber, Fjord taunted Lythir by insisting that there should be no hard feelings between them.[2]


Leylas Kryn[]

Lythir showed Leylas Kryn ("The Bright Queen") all the honors and courtly manners she is owed as Empress of the Xhorhas Empire.

Zethris Olios[]

After the fight in the Ashkeeper Peaks, Lythir was reassigned to the court of Lady Olios in Asarius (possibly as a punishment for his failed ambush).
