Wraith culling beam
(Redirected from Culling beam)
Energy field emitted from Wraith Darts, transporting anyone in its path aboard. Darts use the culling beam to capture victims from the Wraith's human herds, storing targets in a sort of memory buffer. The enables ships to capture many victims and bring them back to the Wraith hive ships for consumption -- a culling.
The beam appears to be a highly charged energy barrier, which moves between the ship and the ground in a sweeping motion, like a net being cast.
Rising, Part 2 - Wraith arrive on Athos and use culling beams to capture several humans and Athosians.
