Weather spire
From Halopedia, the Halo wiki
The Forerunner weather station is a weather control facility set on an unknown Halo installation. The facility likely provides for the artificial weather of the installation, as well as maintaining the atmosphere and climate. The weather station also forms the setting for the Halo: Reach multiplayer level Tempest.[1]
Description
The weather station is situated near a large body of water, with two beam-emitting buildings projecting a blue energy beam into the sky. In the water, there is also a line of large pylons with lightning pulsing at the caps.
