Holding pens are a terran technology.
Three such holding pens were present in a Moebius Corps facility, each housing protoss captives abducted by the Tal'darim to be experimented on and turned into hybrids. Dark Prelate Zeratul and Praetor Talis' forces destroyed the holding pens, freeing protoss inside.[1]
