Desdemona

Desdemona, also known as Dez, is the leader of the Railroad in the Commonwealth in 2287 and an optional antagonist.

Background
Desdemona is the current leader of the mysterious and secretive organization known as the Railroad. Her cautious nature and professional demeanor make getting to know her difficult. As leader of the Railroad, Dez is in charge of day-to-day operations and maintaining contact with the widespread network of safehouses.

Not much is known about her history. Dez first signed up with and joined the Railroad around September 2276, serving under Pinky Thompson. Desdemona was voted into the Alpha position following the resignation of Thompson around December 2277.

Other interactions

 * The Sole Survivor must seek her aid after dealing with the Courser, and getting his chip; as she and her people are the only ones who can decode it.
 * If the player character does not speak to Desdemona prior to entering the Institute and accepting a mission, she shuns the player character and the Railroad quest line ends.
 * If one is a Railroad agent but is Banished from the Institute then this also ends the Railroad quest line as the player character remaining undercover was vital to the plan. Desdemona encourages the player character to stop the Institute with the Commonwealth Minutemen as she sees it as the best remaining option for protecting the synths.

Appearances
Desdemona appears only in Fallout 4.

Behind the scenes
Desdemona is a character in William Shakespeare's play Othello.

Bugs

 * After completing the main quest line with the support of the Commonwealth Minutemen, if on good terms with the Railroad and the Sole Survivor returns to their hideout, Desdemona will speak of Glory as if she had died even though Glory can be seen walking about. If trying to interact with Glory she will stay silent and not say any dialogue.
 * In her speech to Railroad HQ informing them of the Sole Survivor's successful infiltration of the Institute, she may incorrectly refer to them as "Wanderer" even if they chose a different code name when joining the Railroad.
