Szeth-son-son-Vallano

Avado, a traveling merchant, took Szeth in after finding him on the road and carried him toward Jah Keved without knowing he was Gavilar’s assassin.

Szeth is compelled by the Oathstone to serve Makkek, carrying out assassinations and other violence at his orders. Makkek treats him as a weapon and grows increasingly ambitious in using him.

The Parshendi had possessed Szeth’s Oathstone and later discarded it as they fled Kholinar, leaving him to recover it and continue his life as a Truthless.

Taravangian controls Szeth through the Oathstone and directs his killings. He describes them as men of one heart because both bear guilt for deaths, though Szeth is horrified by Taravangian’s secret killings of patients.

Szeth is bound by Shin tradition to carry his Shardblade until death, when the Stone Shamans are to recover it from whoever killed him.

Vstim once acquired Szeth, then a Truthless, from Thresh as a servant. Vstim remembers him as the best servant he ever had and regrets trading him away.

Szeth carries out the Parshendi mission to kill Gavilar. He kills the king, though he does not understand why the Parshendi ordered the assassination.

Szeth refers to the slaughter he committed in Alethkar, an episode that nearly toppled the kingdom and is associated with Kaladin’s later conflict with him.

Szeth killed Took on Makkek’s orders as part of the effort to conceal the secret of the Oathstone.

Szeth is ordered to massacre King Hanavanar's feast and kills him after the king's attempted trap and defenses fail.
