Forum:Batarian first contact date

Can anyone tell me what the source of this assertion: “The Citadel Council made first contact with the batarians in approximately 200 BCE, and granted the batarians an embassy on the Citadel a century later.”? I didn’t found confirmation in the Codex, books, comics, game texts etc. And the “Galactic Codex Essentials edition 2183” doesn't mention batarians at all.--Alexpolt (talk) 07:00, October 29, 2013 (UTC)
