Decimus Sector
From Transformers Wiki
The Decimus Sector is the best place in the galaxy to go if you want to be forgotten. The slice-thieves operate out of the sector before selling their ill-gotten gains on the galactic black market.
Fiction
2019 IDW continuity
By the time that the Tether had fallen, Alpha Trion's search for ancient Cybertronian artifacts had led him to the Decimus Sector. Storm Horizon Part 1 Knowing that Spinister's crew had mapped the Black Sphere region, he bargained for usage of a Kworian starship, eventually finding himself in Soundblaster's company. Though Trion had left a series of signal markers, their proximity to the black hole at the system's centre gave an exaggerated account of how long he'd been gone, Storm Horizon Part 2 causing Cybertron to send Ultra Magnus after his mentor.
When the Fist of Iacon arrived in the Sector, they shot down an enemy ship over Kworia. Exploring the planet, Ultra Magnus found the slice-thieves' central operation. Outmaneuvered by Spinister, Magnus found himself forced to aid the slice-thief in finding Alpha Trion. Storm Horizon Part 1
Heading deeper into the Sector, the Fist of Iacon eventually made its way to the Black Sphere, picking up the beacon of the Krm'zik on the planet Obsidar. Descending to the planet, Magnus crossed paths with some angry natives who pointed him to the Krm'zik, explaining how they were pressured to attack him. Entering the craft, Magnus was ineptly attacked by Octane, Spinister's true target. As the villain monologued, Magnus called in Victory Leo to back him up. After Magnus grounded Spinster, Alpha Trion and Soundblaster appeared to him by hologram, explaining what had transpired before their ship came under attack. Storm Horizon Part 2
Donning space armor, Magnus cut his way through the Kworian fleet and breached Soundblaster's ship. After Magnus defeated Soundblaster, Trion managed to trigger the craft's emergency propulsion drive, allowing them to evacuate before the ship was swallowed by the black hole. Boarding the Fist of Iacon, the group managed to escape back to Cybertronian territory but discovered that, due to time dilation, they'd been gone for seventy cycles. Storm Horizon Part 3
