FangTheCat ((Ah, Stacks. Let me just translate that into actual fleets and... you said 3 Patrols, right?))

The Coreship finally arrives, right in front of the three Patrols, sporting never-before-seen Trader-Class ships sporting an off-beat color scheme... and weirdly enough, an Explorer-class Shuttle, too.
/Transmission Start/
The Core-AI spoke with an accent and a very sarcastic manner. "Ah, a welcoming commi'tee, Splendid. You Pussycats are proving to be a spot of a bother, aren'cha?"
/Transmission End/

The Shuttle seems to be going forward with clear intention of boarding the base, and the Coreship, as well as its escorting "Patrol Cruisers," lets loose a volley of missiles that bob and weave through the DC Formation... if those readings are truly Collective identifiers, anyway. The Warriors responded in kind, not holding back any firepower whatsoever, but the effective screen of Heavy Defender droneships prevents any major damage getting through to the shuttle.
A Smaller Rift-Signature is detected inside the base (seen with a sort of mockup to the right) of the Tribe - confirmed when a bright yellow portal opened right in the way of the Kel'Shir, who were trying to escort a boy away. Out stepped a holographic figure that seemed to be three times the size of an average humanoid - a little bigger than the Kel'Shir Heavy, but about the same size as Darkfoot's Sidera form. It glows as yellow as the portal and has on a visor of some sort. It has two arms where the shoulders are perfect spheres much larger than the segments that make up the arms and forearms.
This Avatar seemed to be surrounded in literal code, and is accompanied by androids with formal-looking armor and very basic weapons. They stand weapons armed, and a standoff ensues once the Avatar makes his presences known.
He bows. "Digital-Condescending at your disservice. I hope I'm not being too rude."
