The Suellk Invasion was an attack on the githyanki and githzerai populations of Ghífthauk. The Suellk made the transit from the moon Ráglauth to Ghífthauk via a massive void fleet. This fleet, the Revered Minds, simultaneously assailed three outlying settlements. In each assault, they arrived unexpectedly and were initially unstoppable.
One of the most notable items employed in this conflict were Silver Mirrors; these arcane devices facilitated the provisioning of an invasion from a source located a world away through the use of another Silver Mirror.
In the year 150 of the Horgon Era, the githyanki and githzerai populations of Ghífthauk were subjugated by the formidable Suellk race, commencing an extended period of bondage lasting over fourteen centuries.
