Rescue of Eos Elara

The Rescue of Eos Elara takes place in Across the Void, Chapters 19 and 20.

Prelude
In Chapter 18, Admiral Deimos and Vanguard Marshalls Eos Elara and Zekei Sentry journey to Ocana to help the Marshall team under attack by the Void. They find themselves severely outnumbered as soon as they land, though, as the Void lay waste to the planet's inhabitants, their homes, and everything else in their path simply to chase down the two Marshalls that had been assigned there. As Deimos and Zekei battle Void soldiers around them, Eos tries to help Aquari save her partner, Jupiter. However, when it turns out that Jupiter has already passed away, Eos and Aquari have to fight to keep themselves alive.

When Prince Barlow makes himself known, Eos is surprised. At first, the Marshall assumes Barlow is there to help, but soon realizes that Barlow is on the side of the Void as the other man believes the Void will bring "peace" to the galaxy by destroying all life. Eos has the opportunity to stop Barlow from killing a group of civilians or watch in horror as Barlow causes a biohazardous waste canister to explode above them. A Void soldier rushing at Eos eventually distracts him enough to allow Barlow to kick him in the chest and pin him underwater. Deimos comes to his rescue just in time by punching Barlow, freeing Eos from the prince's clutches and giving Zekei enough time to help him back to his feet. At one point Barlow manages to knock down all three Vanguard, yet Eos is still able to shoot and explode another canister of biohazardous waste at a wave of Void soldiers, stopping them in their tracks. In the end, however, more Void soldiers rush at the Vanguard, enough to overwhelm and knock them out. In his last seconds of consciousness, Eos turns on his VSS tracking device hoping that his sibling, Captain Elara, will find him before it's too late.

Rescue
In Chapter 19, Captain Elara's VSS unit, Vee, links up with Eos's VSS unit and discovers that he is not on Ocana but is parsecs away in an uncharted region of space. Even though the Atlas has orders to fly directly to Cyber for the peace talks, Captain Elara decides to make a "detour" to find Eos and Zekei. The ship comes across the Void Graveyard, where hundreds of thousands of Vanguard ships lay destroyed. There, Eos's and Zekei's ships return to the Atlas under automated recall protocols and Sol notices that the Void ships in the area are orbiting a large planet that are not listed on their star charts. Oberon states it's the rogue planet under Void control, and Captain Elara and he surmise that Eos and Zekei must have been taken there.

Planetside, Void soldiers strap Eos, Zekei, Deimos, and Aquari into a rocket each. Their leader, Quandry, emerges, boasting that they will destroy the Vanguard just as the Vanguard tried to silence them centuries ago. Quandry asks Eos who is his favorite Vanguard and whoever he answers is tortured by Quandry; if he chooses himself, Zekei is tortured instead. Afterwards, Quandry notices Deimos's uniform and how it differs from the others. Eos can convince Quandry that Deimos is not worth killing or follow her orders and step down, allowing her to sacrifice herself. If he chooses the second option, Quandry launches her rocket into the sky and it explodes into fireworks.

After cloaking the Atlas, firing on the Void patrol ships, and/or steering the Void ships into their own wreckage and destroying them, Captain Elara lands the Atlas on the dark, barren surface of the Void planet. While Meridian stays behind to tend to Holmes in the med bay, and Sol, Corvus, and Argo stay to take care of the passengers, Kepler, Titania, and Pax join Captain Elara in his/her rescue party. Zaniah regrets she cannot help for fear that the planet would consume her and Oberon is afraid he'd be a liability with his injury.

The rescue party quietly approaches the Void party site. While Vee and Titania wait with the hovercycles, Captain Elara, Pax, and Kepler steal Void soldier uniforms and disguise themselves. Captain Elara runs into Procyon Thamuz, who has been supplying the Void with weapons, but brushes him off when Kepler finds the rockets with Eos, Zekei, and Deimos (if she is alive) inside. Captain Elara can have Kepler or Pax cause a distraction with the surrounding Void soldiers or ply them with more alcohol, while the other two break the Marshalls out. Before Captain Elara can rescue Aquari, he/she crashes into Procyon again who recognizes him/her this time. Captain Elara can bribe Procyon to look the other way in order to rescue Aquari and escape, or let him sound the alarm. If Captain Elara chooses the first, Aquari fights alongside the crew and saves Vee's life in the final battle. If Captain Elara chooses the second, Aquari is tortured by the Void and joins them in their battle against the Atlas and her crew.

When the Void soldiers notice that the rescue party and prisoners are escaping, they attack. Titania and Vee arrive with the hovercycles. Pax and Aquari take one, Eos (with or without Deimos) take another, and Captain Elara can choose to ride with Zekei, Kepler, or Titania; the remaining two will ride with each other. Void soldiers try to jump on the hovercycles as they race by but fancy flying and/or weapons help knock them off. Once onboard the Atlas, Captain Elara gives the orders to take off and the ship leaves the planet.

Aftermath
If Eos did not save Admiral Deimos, he is despondent about her death and blames himself. Oberon tells him that he needs to do something reckless to distract himself temporarily, and Eos can choose to join Oberon in a moon simulation if he wishes. Meanwhile on the bridge, Captain Elara tells the crew to get some rest. If he/she chooses to, Captain Elara can also get romantic with Zekei.

The next morning, Captain Elara confers with Lyra and is told that the peace summit on Cyber was suggested by Prince Barlow himself. Aware of his true allegiance now, Captain Elara knows the Atlas, the Vanguard, and the Jura are heading into a trap.
