Sanctum of a Thousand Eyes
From Warhammer 40k - Lexicanum
The Sanctum of a Thousand Eyes is a section of the Imperial Palace.[1]
This armoured bastion of the Dread Host Adeptus Custodes is lit with electro-braziers and lumens of immense size, all angled to under-light the five hundred enormous eagle statues that line the sanctum's upper battlements. Each is as large as a Super-Heavy tank. Legend says that these structures can perceive disloyalty in any they gaze upon. To some extent this is true, for the eagles contains a complex array of augurs, servitor cognition banks, and multi-spectral listening devices that feed the Dread Host with valuable information about possible threat to the Golden Throne that need their immediate reaction.[1]
