Invasion of Neptune

The Invasion of Neptune, also known as the Siege of Neomuna was a massive conflict that unfolded on Neomuna after the Witness's attack on the Traveler. After communing with it and discovering the location of the Veil, a paracausal object related to the Traveler, the Witness ordered Calus, its newest disciple, and his forces to invade Neptune and secure the Veil. This prompts Osiris to stow away on one of the Shadow Legion’s carriers in order to stop the invasion. The Guardian follows him on orders from Ikora Rey, and after sabotaging their carriers, The Guardian and Osiris make their way to Neomuna via Drop Pods. From there, they would befriend and ally the Cloud Striders Nimbus and Rohan, and along with the Imperial Cabal, would work to stop both Calus and the Witness.

After the defeat of Calus, the conflict would spill over into the flagship of the Witness, Essence, as a team of 6 Guardians would confront Nezarec, Final God of Pain and permanently put an end to both him and his haunting of the CloudArk.

Prelude
The Neomuni have known about the Vex for many decades prior to The Witness's arrival into the Sol System and have fought them off on numerous occasions as the Vex attempted to raid the CloudArk for its sensitive data. Additionally, both The Guardian and Osiris boarded a Shadow Legion ship shortly before the fleet jumped to Neptune's orbit. The Guardian would then fight through the ship before they and Osiris used the Drop Pods to land on Neomuna but not before the seige began/

First Contact and Discovery of the Radial Mast
The Neomuni would have their first face-to face encounter with the brunt of The Witness's forces when Emperor Calus landed his ship, the Typhon Imperator, into Ahimsa Park. The sector was quickly overrun by Vex and Cabal alike and the Cloud Striders on duty, Rohan and Nimbus, retreated to Strider's Gate. The Cabal were followed shortly by The Guardian and Osiris, the former landing in Ahimsa Park and the latter landing in Strider's Gate. The Guardian would cut their way though the Cabal forces to Strider's Gate where they would encounter Strand for the very first time. The Guardian would use this new found power to destroy the Cabal that would land in Strider's Gate but would not be able to reach Osiris before they were exhausted.

Luckily, Osiris would be saved by the Cloud Striders after fighting off some Cabal and a Tormentor. The Cloud Striders would then spend the next few hours destroying some of The Witness's forces before regrouping at Strider's Gate. After discussion with Osiris and allowing him to stay within the Hall of Heroes, the Cloud Striders would agree to help The Guardian reach The Veil. The Guardian would fight their way through Zephyr Concourse and into the Esi Terminal where they would encounter more Shadow Legion forces, this time with Light suppressing technology. The Guardian would defeat a Shadow Legion commander Vul'ourn, Shadow Legion Supply Master despite this only to realize that the area surrounding The Veil was firmly within Shadow Legion hands. The Guardian's Ghost would then transmit a conversation between The Witness and Emperor Calus, with The Witness ordering their disciple to destroy The Veil using the Radial Mast which was located deep within the Typhon Imperator. The Guardian would retreat from the area and regroup with their allies to discuss further plans.

Some time during these events, the Vex, lead by Parthenios, Drifting Mind, managed to take control of the CloudArk's power supply, inhibiting the Neomuni's ability to effectively defend their homeland.

The Raid on the Typhon Imperator and Coalition Contact
With The Veil and the CloudArk in direct jeopardy, the Cloud Striders and The Guardian both agreed to raid the Typhon Imperator. Fighting through Ahimsa Park, the Guardian would board the massive ship and sneak deep into its complex walls and hallways, dispatching groups of Shadow Legion as they went through. They would also sabotage and destroy a small fleet of ships by overloading them with energy. When The Guardian approached the Radial Mast, it was revealed that it was a trap laid out by Emperor Calus. The Guardian fought off seemingly endless waves of Cabal and Taken and it looked like The Guardian was trapped within the Typhon Imperator. However they would be rescued by Empress Caiatl and her band of Loyalists, blowing open a barrier and allowing the Guardian to slip away on their Sparrow.

The Vanguard established contact with Neomuna and an ad hoc alliance was formed between the two. However, the Neomuni were still skeptical of their new allies, unsure if the alliance was simply an excuse to conquer Neomuna without any fighting.

CloudArk Repaired and Destruction of the Radial Mast
The next mission The Guardian and the Cloud Striders would undertake would be a repair of the CloudArk's power supply which was still under the control of the Vex in Límíng Harbor. The Guardian would smash through the Vex defenses surrounding the CloudArk reactor, finding more pockets of Strand along the way to assist them. The Guardian would eventually encounter the leading mind, Calixte, System Ward Finality, and destroy it and breaking the CloudArk free of Vex control. However, the Shadow Legion were closing in on The Guardian's position in order to kill them, lying in wait to both destroy The Guardian and the CloudArk in one fell swoop. The Guardian would eventually escape the ambush with the usage of Strand with the reactor sustaining minor damage. This resulted in the Neomuni being able to take control of their defensive measures and assist both The Guardian and the Cloud Striders in the defense of Neomuna.

With the CloudArk secured, The Guardian attempted to further their connection and control over Strand. They departed to Maya's Retreat in order to meditate on their usage of Strand but were ambushed by Vex forces. These Vex were dispatched by The Guardian's new Strand abilities which lead Osiris and Rohan to believe that they were ready to destroy the Radial Mast. With the assistance of the Coaltion, they located the Radial Mast attempting to link to The Veil within the Irkalla Complex and smashed through Shadow Legion Forces to get there, using the Coaltion's Drake Tanks to break through the walls of the complex and sneak their way through. With the Radial Mast activated and the Shadow Legion closing in, Rohan jumped into its construction and attempted to delay its connection with The Veil. Meanwhile, The Guardian destroyed the Shadow Legion forces that had swarmed the area using Strand but was unable to hold onto their control over the energy to destroy the Radial Mast. With no other option, Rohan brought the mast onto him and destroyed it but killing him in the process. From the remains, the Guardian recovered Rohan's core and delivered it to Nimbus.

In the Hall of Heroes, Rohan was laid to rest amongst the other Cloud Striders and Nimbus was named the lead Cloud Strider in his place.
