Sekrion, Nexus Mind

"The Vanguard's intelligence sources now believe, with good confidence, that Sekrion oversees the expansion of the Vex network through the crust of Venus."

- Grimoire Description.

Sekrion, Nexus Mind is a massive Vex Hydra that lives deep within Venus. It is the Axis Mind in charge of converting Venus into a Machine World. In The Dawning Sekrion returns as Sekrion, Subverted Mind.

Overview
"Far below the Ishtar Academy, the Vex have set something in motion: a world-eating machine transforming Venus into another link in their intergalactic chain. This Nexus must be stopped and the Mind that controls it destroyed."

- Ikora Rey

Sekrion oversees the Hezen Protective in the expansion of the Vex network through the crust of Venus using its impressive computational capacity to coordinate between Minotaurs operating in the construction role. However, a fireteam of Guardians was dispatched by Ikora Rey to end the Axis Mind and hamper the Vex effort to incorporate the entire planet into their network.

The loss of Sekrion brought a setback to the Vex as a significant node of the Nexus network is lost, prompting Theosyion, the Restorative Mind to bridge time and bringing the Vex Mind back from the past to resume its duties. Its efforts were however uncovered by Ikora and the Guardians sent to destroy Theosyion, preventing any alternate outcome that would replace Sekrion's destruction.

The Dawning
"The mind is wielding a sufficiently upgraded chassis." "I bet bullets still work."

- Ikora and Cayde-6

The Vex still continue to struggle since their numerous losses to the various forces of the Solar System, namely the Guardians and the Taken. To counter the Guardians and restart the process of converting Venus into a machine world, the Vex uses its ontological technology found in the Vault of Glass to repair the Nexus Mind. Cayde-6 refers to this plan being a fearful, desperate plan for the Vex.

However, Ikora Rey's Hidden intelligence discovers this plan and so organizes the Guardians to destroy it before it can complete its work, all while dealing with the remaining Taken on Venus. After being guided by Ikora and Cayde-6, the Guardians reach the restored Nexus Mind, which was corrupted by the Taken as Sekrion, Subverted Mind. Despite its restored chassis and newly upgraded abilities, the Taken Vex Mind is destroyed once again.

Gameplay
Sekrion is the final boss of The Nexus strike. It fights like an ordinary Hydra, but fires its Aeon Maul more rapidly. It stays in the center of the arena, allowing Guardians to avoid its fire by ducking behind stone pillars. Additional Vex will spawn to flush out the players around the room, so players should be wary to not completely focus on the boss.

The Nexus: Revisited
In the Revisited version of the strike, Sekrion makes a return as the final boss. Once again, it stays in the center of the arena, pounding Guardians from afar with its Aeon Maul. It has gained a special mechanic: like the Oracles, if you get Marked by the Void then every Guardian must step in a pool of Light to remove the debuff, or else die after your screen goes completely black. Alternatively, in the Taken version of this strike has players remove Sekrion's shield by firing an Aegis at him so Guardians can defeat him.
