Once constructed, it gives Foremen access to a wealth of new units and structures. Devastator Warships and Planetary Assault Carriers (with a Signal Transmitter present) can be called in from the Gravity Stabilizer, Annihilator/Reaper Tripods can be summoned from the Warp Sphere, and with the conjunction of the Stasis Chamber, Masterminds/Prodigies can be sent in through the Portal. It also allows the construction of the Signal Transmitter, Storm Columns, the Warp Chasm and the Rift Generator superweapon.
