{{main|Slann}}

The Old Ones did not appear in the first edition material of Warhammer 40,000. There was a similar race in their place in the form of the [[Slann]] or Old Slann that featured in [[Warhammer 40,000: Rogue Trader]] and [[Codex Titanicus (1st Edition)]], in which they made early contact with the Eldar and taught them the technology to create the Webway. The former source also states that the Slann were responsible for the genetic manipulation of various races and suggested that the Jokaero are one of their creations. In third edition material, starting with [[Codex: Necrons]], the Old Ones are first mentioned and their backstory elaborated by stating they genetically manipulated early life and fought the an ancient war against the Necrons. Future material such as [[Codex: Eldar (4th Edition)]] and [[Codex: Chaos Daemons (4th Edition)]] also state that the Old Ones had a hand in teaching the Eldar to make use of the Webway whilst [[Codex: Dark Eldar (5th Edition)]] mentioned that they actually created it in the first place.
