This key used to be the only way players can attain access to Councilor Vay Hek's assassination node until Update 15.13, with the access requirement replaced by simply having a Mastery Rank of 5. This item currently serves no purpose, along with the Beacons that make it. As of Update 16, all blueprints to this key are removed from all players. However, players with built keys are still able to access an alternate Boss Node on Earth against Vay Hek, the only difference being a 27 - 30 level range for enemies.
