No human has ever interacted with an Elg.
The first recorded encounter between an Elgan Ambassador and humans took place in 2304, when a team responding to a distress signal from the derelict freighter Salutator were stalked and had eggs planted in their stomachs by a horrible black armored seven-foot monster. Unfortunately they’d never seen that movie, so ultimately the survivors just blasted it to pieces, at which point they realized it was a robot. Later they learned there was no freighter called Salutator registered anywhere in the region.
The second Ambassador took the form of essentially an ambulatory turd with big, expressive eyes and a telescoping neck. It successfully befriended a small, lonely boy in a community halfway between urban and rural, but he maintained the secret too well, and no government agents ever captured the Ambassador to experiment on it. After nearly 40 years of continuous operation, it broke down and was passed down in the family as an unusual piece of artwork.
For most of the 24th century and into the 25th, a series of Ambassadors visited human planets in the form of extremely stealthy spaceships crewed by little gray humanoids with massive black eyes. Their approach was to abduct humans from farms or isolated roadways, poke and prod them while enigmatic statements readable as either hopeful or menacing, and then partially wipe their memories. This resulted in everyone visited by the Elga being dismissed as attention-seeking or mentally ill.
The final, ultimately successful attempt by the Elga was to have one of those Ambassador ships appear in full view in a highly populous system, warn humanity of a terrible alien empire bent on galactic conquest, and invite them to join a cooperative alliance of many cultures spanning a wide swath of the galaxy, for trade, cultural interchange, and mutual defense.
(Of course, then the Elga discovered that for some reason the humans now expected there to actually be an inter-species cooperative union threatened by an encroaching evil empire, but the story of how the Elga trolled the P’a’a, and the ensuing eight wars and counting over the past century and a half, lie outside the scope of this document.)
Today the Elga are regarded as close allies by the majority of human worlds, respected as the founders and senior members of the Cooperative United Federal Alliance of Worlds and Sentiences. Their robotic Ambassadors trade information and broker negotiations on hundreds of worlds, while their automated fleets help defend against pirates, raiders, Dwiro, and both the Ri’it P’a’a and the P’a’a Krii.
And to this day, no human has ever seen or interacted with an Elg. Even the rare visitors to what the Ambassadors insist is their homeworld see nothing but their robot servitors in a barren, admittedly beautiful, wasteland of massive crystal formations, beneath an eternally thundering sky that never rains.
Some people think they’re dead, the Ambassadors all that’s left. Others think the Ambassadors made them up, and they’re actually just a machine race with a weird sense of humor. Still others think the Elga live hidden on their homeworld, beneath the rocks or in the clouds.
They’re all wrong.
