- Main article: Lucien Lachance#Biography
The Spectral Assassin was known as Lucien Lachance in life, and was a Speaker of the Dark Brotherhood during the Oblivion Crisis in 3E 433, shortly after the assassination of Emperor Uriel Septim VII. Lucien was later murdered by his speakers of the Black Hand after being mistaken for being a traitor, which was truly Mathieu Bellamont, who sought vengeance on Lucien after the assassin killed his mother. The Night Mother recognized Lucien as being loyal to the Brotherhood, keeping his soul in the Void of Sithis, and had his spirit summonable by the Brotherhood as a reward.
He often comments on his days working for the Brotherhood, on the Dragonborn's decisions during the Dark Brotherhood questline, and on the fact he and they are connected through the Void.

- Casting certain effects on Lucien's ghost, such as Healing Hands or Courage, will cause his body to lose its spectral effect and become visible normally. This will reveal that he is wearing the shrouded robes, the same outfit as Gabriella and Festus Krex.
- His ghost uses a steel dagger when fighting.
- The voice actor for Lucien Lachance is Wes Johnson, who reprises his role from Oblivion.
- Lucien also greets Shadowmere as an old friend when he is close to the horse.
- When Lachance comments on the quest "To Kill an Empire", he mentions apples. This refers to when Lucien gives a poisoned apple during the Purification quest in Oblivion, and had a barrel of poisoned apples inside Fort Farragut.
- One of Lachance's comments about "To Kill an Empire" refers to the Mythic Dawn killing Uriel Septim VII.
- Lachance's line "I live... again." may possible be a reference to the 1992 horror film Army of Darkness.
- Lucien's line "I am reminded of another Listener, a protege I knew long ago. So long ago..." likely refers to the Hero of Kvatch.
- Although one cannot technically interact with Lachance (as he is a summon), he is able to be healed by Restoration spells such as Heal Other and Grand Healing. He also enters a "yield" stance when critically injured, like any other character.
- If Lucien is near a Bard who is singing a neutral song, such as Ragnar the Red, he may clap his hands in a drunken manner, cheering on the Bard with the rest of the patrons.
