This article is about the ritual. For the comics, see Stargate Atlantis: Wraithfall 1.

Wraithfall is a ritual employed by the Karrans. A long time ago, the Karrans made a deal with the Wraith. The Wraith would not cull on them or destroy their planet if the Karrans offer the Wraith five of their most valuable members. The ritual was employed every three months. (SGA: "Wraithfall 1")
