Harbinger

Teal'c took the first step moving into the wavering portal in front of him. He felt it pull him forward almost as if he was being thrown into it. His familiar homeland gone and far behind him, he knew what he had to do. The Overlords had told him where to find it. As the rift of the portal closed behind him, Teal'c stood underneath an unknown sun in an unknown land. This was his first time leaving the Far Realms, plunging into a new plane. He didn't know what to expect but this world fascinated him. The warm breeze, the bright sun, the strange and fierce animals roaming across the land. Armed with only a few trinkets and the burden of his people, he turned his head and moved on.

The Harbingers reside deep within the Far Realm and are rarely seen since they usually operate through agents to make their deals. It has been speculated that the Harbingers make these strange requests because of strange fetishes or gruesome culinary tastes, but it is more likely that they perform experiments on these subjects. Regardless of the possible danger, their requests are often granted by fringe groups because of the usefulness of their services, including the psionic powers they offer in return, are extremely valuable.

The Harbingers are controlled by the oldest and most psionically powerful of their kind. These leaders called Overlords, control and guide the hive mind of their species and act as the will and intelligence of the collective.

Alien Form

The Harbingers resemble human-sized bipedal creatures with a dark exterior, and large intricate horns on their tapering head. The Harbingers possess two pairs of arms, a long tail, a small set of many red eyes, horns which can very greatly in size and complexity and black or blue skin.

Solitary Harbingers are likely rogues and outcasts. Most Harbingers belong to a colony of siblings devoted to a small group of Overlord's- an especially powerful Harbinger that leads the hive mind. An Overlord telepathically dictates its desires to each individual Harbinger within 5 miles of it, for it is able to hold multiple mental conversations at once.

Hive Minds

All Harbingers possess telepathic power, using it as both their form of communication and thought process. Some Harbingers can be very rational and calculating, but others are empathetic, timid, or hot-tempered. However, at the same time they are all foreigners to the Material realm, unaware of what lurks within and attempting to accumulate the vast stores of knowledge now open to them.

Rift torn world

Reported sightings of the Harbingers has existed for thousands of years but the mysterious aliens were widely dismissed as myths. Some speculated that they would use their powers to open portals from the Far Realm into the Material plane to fulfill their current interests then leave as quickly as they arrived.
