Eidolon

The Eidolon were a race of beings native to an alternate reality version of the Pegasus Galaxy.

In alternate dimension, the Ancients suffered from a terrible plague that devastated their population who created a Quantum Mirror for some of their population to escape to another dimension. With their civilization collapsing, they attempted to create a second generation of their kind by seeding Humans colonies in the galaxy. However, these colonies themselves were ravaged by the plague which led to both the Lanteans as well as their successor race facing extinction. Thus, in desperation, the Lanteans sought to create a race that would serve as their successors and began experimentation on the Iratus bug. Under a controlled setting, they genetically engineered the Iratus bug to be combined with Human DNA with this resultant race being bred to not feed off sentient beings. Thus, the Eidolon were created who were their reality's version of the Wraith though were more benevolent as well as peaceful species that did not hold the need to feed on sentient beings.

In time, the Lanteans perished and left the Eidolon to develop on their own though their final act was providing the Ancient gene that allowed them access to Lantean technology. This race developed much of the physical features of the Wraith with their kind consisting of males, females as well as Queens though lacked the drones. Furthermore, they retained telepathic abilities though lacked the means to be sensed by Wraithkin. They came to hold great respect and even revere the Ancients who they called the Creators. With their society developing, the Eidolon formed pronounced Human behavioral characteristics. As they developed, they managed to create a mixture between Wraith and Ancient technology. This allowed them to create advanced scientific vessels with sensors able to pierce through cloaks.

By the modern age, the Eidolon discovered a Quantum Mirror over a moon linking their reality with the mainstream one. Under the leadership of a Queen, she decided to send her daughter Trishen through the Stargate styled Quantum Mirror to investigate the other side. Wearing an environmental suit, she met with AR-1 who initially believed her to be part of an elaborate Wraith trap. At this time, a Wraith Hive ship arrived which forced Colonel John Sheppard to work with the Eidolon in fighting the Wraith whilst working to destroy the Quantum Mirror.
