Slaughter on the Reverence

"Unidentified vessel, this is the Republic Cruiser Reverence. prepare for tractor beam lock. Failure to comply will result in your termination."

- Statement given by the Reverence to both Arek Saris and Antimatter Squadron upon detecting their ships.

The  occurred in 19 BBY when Arek Saris was taken aboard the ship and killed the crew. Ganner Slarwlaker and Antimatter Squadron followed, but were unable to prevent him from escaping to Mandalore. Afterwards, the team met Dylan Antiunknown for the first time, unaware of his true identity.

Prelude
On the run after the Felucia Jailbreak with Ganner Slarwalker and Antimatter Squadron close behind, Arek Saris decided to accelerate his Master's plan to raise an army of Sith by heading to Mandalore immediately to seek out Captain Xux. However, en route, he was intercepted by the Reverence, a Republic experimental crusier. At the same time, Dylan Antiunknown had secretly hidden away on the cruiser, using it to get to Mandalore to meet with Garrick Clyine.

The battle
Upon arriving, Arek Saris introduced himself to the clones who greeted him as Darth Massikus before going on a violent rampage across the ship, eliminating the entirety of its crew save for Dylan, who completely avoided detection despite hiding directly under the bridge.

Shortly after, Ganner and Antimatter Squadron arrived and landed on the ship intent on hunting Saris down. The group split up in order to cover more ground quickly; however, this also gave Cade Slarwalker (who had just become aware of his true identity and repressed memories after enduring severe torture on Felucia) the opening he needed to stun Blaze Terrant and escape with the shuttle the team had taken onto the Reverence.

Ganner, Hans Novastar, and Siri Tokolighter tracked and cornered Saris, who took Siri (his secret apprentice) "hostage" and escaped. Heading to the bridge, Ranulph Darkhitch encountered Dylan, practically raving, who he cornered and tried to interrogate with little success.

Aftermath
After Saris left, Ganner spoke to Dylan, who explained that Saris spoke on the bridge about Pre Vizsla, Mandalore, and a second objective. The team left to puruse him, and Dylan returned to the Brotherhood HQ.
