super-weapon, Ancient
THE STARGATE OMNIPEDIA
SUPER-WEAPON, ANCIENT
A powerful technology created by the Ancients and incorporated into the Atlantus outpost, deep beneath Antarctica's frozen surface (and likely on Proclarush, as well). A user sits in the outpost's command chair to control the weapon. The device appears to interface directly with the user's mind, allowing one to select a target to be destroyed. Countless quantities of Ancient drones emerge from under the outpost and stream toward the target, not unlike a swarm of bees, cutting through even the most powerful Goa'uld shield technology.
