"I thought we were friends! Was I wrong? Of course I was wrong. Wrong to be your friend. Wrong to keep your secrets. Wrong to trust you. But I feel smarter, now. I do. Smart enough to know the truth. Smart enough to tell you that, Francis, even in this infinite universe... There's nowhere to run."
Elden to Francis (from Prometheus: Fire and Stone)

Elden was a construct part of the crew of the Geryon sent on a 'salvage mission' on the moon LV-223. Elden began violently mutating after he was injected with a dose of Chemical A0-3959X.91 – 15 by astrobiologist Francis Lane, who wanted to use Elden as a filter to see if the liquid could cure his cancer.

Graph showing Elden's evolutionary stages.

Originally a machine, Elden has taken on a humanoid form and looks as if he's been stripped of most cutaneous material. He is done all over in white and reddish tones, with two tube-like tendrils protruding from his back. Elden is capable of fighting multiple Xenomorphs and Predators at once, and is able to withstand a blast from a Plasmacaster without flinching and then regenerate the damaged flesh seconds afterward. His mutation also allowed him to morph his body at will. During a battle with a pack of Predators, Elden morphed the flesh of his stomach into jaws with which he bit one Predator, causing the alien hunter to mutate as well.

He has some control over the Xenomorphs and vaguely reflects their skeletal visage. The tendrils on his back turn out, later, to be an immature extra set of arms.



Elden's "human" form.

Two days before arriving at the moon, passenger Clara Atkinson begins recording a documentary using a PUP-like device. She introduces the camera to Francis Lane and begins talking to him. After the discussion, Francis contacts Elden, who is busy scribbling 'hello' on the walls. Francis tells Elden that if Clara talks to him, don't bring up his "medical condition" (cancer).

Elden and the rest of the crew land on the moon and begin exploring the terrain and are met with a lush jungle, bristling with strange alien life. They later come across a field of deceased mauled creatures and a lake of black goo. Francis becomes intrigued with the liquid and begins examining it, with Elden remaining cautious.

The prime discovery made by the crew however was an old vessel from the colony Hadley's Hope located on the neighboring moon LV-426 — containing a horde of hostile Xenomorphs which they unwittingly unleash.

Mutation and rampage

Separated from the rest of the crew, Francis and Elden take shelter in a remote cave. They uncover the research left behind by the cave's previous inhabitant — a survivor of the Onager crash, Derrick Russell. After reading the survivor's work, Francis deduces that the result of the jungle was due to a crashed alien ship that had released numerous urns of black goo in the process, mutating the environment. Francis determines that the genetic accelerant's mutation process could be filtered to be the long sought cure for his cancer. Francis requests for a reluctant Elden to be the filter, and injects him with a "drop" of the liquid. Elden, frightened, begins mutating violently.

Enraged at Lane, Elden began chasing his "friend", but Francis was able to escape from him and reunite with the crew.

Back at the Helios, a horde of Xenomorphs began crowding outside the ship, with Captain Angela Foster and some other members watching from a distance. Angela suggests that Galgo and fellow members Piper and Higgins return to the Perses to use the ship to drive off the aliens using it's weaponry, whilst putting Francis in lockdown.

Whilst waiting for Galgo's backup, Angela and others witness an unhinged Elden approach the surrounded Helios and the Xenomorphs allow him to open the hatch to the ship.

Galgo, Piper and Higgins decide to take the Perses and abandon the rest of the crew. Elden, knowing that Francis is in the Perses, pilots the Helios and takes off to find and kill Francis.

Personality and Traits

"Hello, I'm Elden."
Elden's signature greeting
Elden was a helpful individual and trustful to people to a fault, as he allowed his friend Francis to use him as a test subject for accelerant, causing a tragic chain of events. After becoming infected and mutating, Elden became more aggressive and violent, going on a rampage and allowing Xenomorphs to kill off survivors. He later calms down and begins to become helpful once again and aids Angela and the rest of her crew.

Elden generally experiences periods of intense blood-lust which can quickly turn into an inquisitive introspection on the nature of life, death, emotions, meaning, violence and other such topics.

Behind the Scenes


Concept art of Eldena from Prometheus: The Complete Fire and Stone.

Originally, the character of Elden was conceived as a female synthetic known as 'Eldena'. After she was mutated by the black liquid, Eldena would have become pregnant with synthetic Facehuggers, later giving birth to the creatures. When one of these robotic Facehuggers impregnated a host, they would have birthed metallic, more machine-like Xenomorphs.
