Dacien Thricedead: a male Half-Elf rogue assassin.

An original member of the Owl’s Bar Adventuring Group, he runs the thieves' guild in Phandalin from the cellar of Owl’s Bar. Recruited by the Zhentarim as an agent, he then used this position to act as a double agent on behalf of the Harpers. Dacien’s true allegiance is to OBAG, but it amused him to subtly thwart the Zhentarim, as he is sympathetic to the Harpers goals. He has since been exposed as working against the Zhentarim who now view him as an enemy.

He is a master of disguise as well as a deadly assassin, and has used these abilities during many intrigues along the Sword Coast. Of note is his taking over the identity of one Marod Wistvain, a fat, rich, gem merchant who's legitimate business in Waterdeep provided cover for fencing operations. Marod worked closely with the Zhentarim as well as Xanathar's Thieves' Guild.

When Dacien caught wind of a plot by the Zhentarim to obtain a powerful weapon which they planned to use on to assassinate officials in Waterdeep, he killed Marod and assumed his identity to gain more information. He eventually recruited a band of adventurers to thwart the plans of the Zhentarim. Once the mission was complete Marod's body was discovered (along with a new will) and all his holdings were turned over to the adventurers who helped Dacien.

Dacien has also served as a mentor to a Kenku Shadow Monk named Rekorak. Rekorak's ability to perfectly forge any documents as well as his ability to perfectly recall and recite messages made him a valuable courier, spy and messenger spy for Dacien.
