Elvi (Artisan, Soul in Dratak: Elves in English) are approximately human sized beings and are from the planet Eldar.
Elvi can easily pass as human by hiding their pointed ears (this is how they can hide on Erset in the Erset Universe).
According to Akasha Records, Elves are a race of zavi created by the Anu as a combination of Leopard and Anu DNA.
There once was a Great Eldar Empire in the Abzu Galaxy.
They spread to Anki which lead to them controlling the Abzu Galaxy for over a thousand years.
The Elvi discovered and maintain RIPgates.
This is why the Elvi language and culture has so permeated the Worlds of the Abzu Galaxy.
The Eldar Empire was overthrown in the Anki Ascendancy Wizard Wars which introduced a massive influx of humans from the Mycenaean civilization from Erset to Anki.
The Helios solar system has hence mostly converted over to Mycenaean/Greek beliefs and names while the rest of the Abzu Galaxy still uses the ancient Elvi language for names and places.
The Elvi tend to be on the arrogant side because they once ruled the galaxy.
The Elvi are the closest allies and trading partners with Humans now though.
Elvi are NOT immortal, but live to be between 550 and 750 years (700 is average).
