The Spire seen from a distance.
SkyTown's Spire Dock is initially a room of SkyTown, Elysia in Metroid Prime 3: Corruption. This room is also the location that holds the Theronian bomb after the completion of this weapon.
Description
The Dock is a large floating pod that has three engines. The Spire appears to have been designed to be seperated from SkyTown from construction. A holding chamber at the top of the Spire can host large items and ships, and is controlled by Aurora Unit 217 from the Aurora Chamber. Three "prongs" of the Spire connect to three portions of the city, so the Dock is also a sort of crossroads. After the Theronian Bomb is used on the Leviathan's shield, the Spire dock is destroyed, and Samus has to cross using Kinetic Orb Cannons instead.
Role
Aurora Unit 217 releases the cables on the Spire, seperating it from the rest of SkyTown with Samus staying on the Spire. The Spire then moves toward the Leviathan. The Space Pirates detect Samus' movement towards the Seed, and send large forces of Pirate Troopers and Space Pirate Assault Skiffs to destroy the Spire's stucture. After fending off the enemy units, Samus deactivates the three thrusters, which drops the Spire onto the Seed Shield, causing a thermonuclear explosion that destroys the shield without having to destroy the shield generators. Samus escapes using an Escape Pod just in time to escape the detonation, having been slightly hindered by a malfunctioning Escape Pod mechanism, which she needed to fix. Samus's Escape Pod then docked back in Skytown, in a previously unused room containing an Escape Pod cradle. The Leviathan was then exposed, allowing Samus to pilot her ship to land inside.
