Covenant pylon

The Covenant Pylon is a Covenant structure seen in Halo: Reach. It is used to block any UNSC scanning equipment and hide any Covenant forces stationed within the "dark zone".

Structure
The building is a dark blue color and has a tripodal construction with three legs, three gunnery platforms, and three curved spines on the top of the structure that slowly spin. These spines emit pulses every few seconds as they spin. A small walkway encircles the whole building. There are plasma cannons on each of the three platforms used to defend the pylon.
