Ballista Storage

Ballista Storage is a room on SkyTown, Elysia. It appears in Metroid Prime 3: Corruption.
==Description==
The room's entrance hallway leads to a small circular room housing a unique spherical elevator that quickly descends to the room's much larger lower floor once the center is reached. The basement floor includes three large ledges underneath a large communication panel each on three of the room's sides. The fourth side is adorned by a statue of a Chozo head. Under this statue, a locked door, powered by two turbines, is in place to prevent access to an Energy Cell. The turbines may be damaged if excess energy is supplied via the Grapple Voltage. The Defense Drone is battled here, and when defeated, it rewards the Boost Ball.

==Development notes==
The room's internal name is 07_skytown_mechanoid, referencing the Defense Drone housed here. The keyword skytown indicates Skytown, Elysia, and the prefix 07 indicates that this is the seventh of 15 main rooms throughout the planet.
The room's internal name is the source of the Energy Cell's coordinates 07S-MEC.
==Trivia==
*The pattern of red circles seen above the Elevator at the top of the room bears a striking resemblance to the red eye designs seen on Aether.
