Thargoid Spire
Thargoid Spire are huge organic structures. They are approximately 6 km tall (3x a Majestic-Class Interdictor). Banshees protect the Spires. Orthrus and Cyclops interceptors emerge from 4 portals of the largest spire.
A Thargoid Barnacle Matrix can evolved into a Spire. The first of which was spotted on October 16th 3309.
