Avkra-Metru

Prophet teleports into the main tower. He enters a special room on the top floor. Windows overlook the city. He would smile, but there are more pressing matters on his mind. The Oracle materializes.
Oracle: "There is a visitor from another dimension in Xia. You should send a retrieval team. I can sense that he is of great importance to future events."
Prophet: "I'll send the team immediately. Where in Xia?"
"The docks."
Prophet goes over to a computer system on the wall and presses a few buttons. A map of Xia appears and with a few more buttons marks the docks for the retrieval team.

The Xiajet is scanned and two drone ships fly out to escort it. They catch up to it and a mechanical voice says,
"Unauthorized aircraft, follow the path we take to land. Any deviation will be taken as a sign of aggression and you will be shot down."
One Drone ship slows to fly behind the Xiajet while the second zooms ahead towards a rectangular building, with various aircrafts on it. The second ship lands and the first one waits in the air for the Xiajet to do the same.

The Xiajet is found to be of fairly advanced tech, though slightly outdated by current Xian standards.

It complies and lands.

The matoran, in a Boxor unit, turns on the mechs smashing them to pieces. He pulls an Olmak from his bag and uses it to open a portal, taking the remains of the mechs with him.

A wall of Nanites forms infront of the matoran. The energy bursts hit the wall, sparing the matoran behind it. Maxilos - the one that was made by Prophet in his home dimension - shoots all five Maxilios from behind, exploding their mechanical heads.
"Wrong move, you never stand in my way."
Maxilos looks different however, having six arms, taller, and has a slight resemblance to the Nanite Swarms met in The Ship and at the Xian Shipyard.
The wall of Nanites disperses and swarms the 7 mechs, reading all the data of this universe, disabling them, and returns to their host, Maxilos.

Maxilos grinds his mechanical teeth.
"Remember."
In a flash of red he vanishes, a small red aura permeating the area.
Dozens of E-X stand in a circle with their IPR's pointed at the mechs.

A drone ship arrives at the city and Silver witnesses the chaos below. He opens the hatch of the ship and jumps out. The ship continues on its way and lands on the roof of the AirSec building.
Mid fall, Silver shoots his IPR at various mechs before finally landing.
"By continuing these actions you chance war. Cease and desist. Then state your purpose for being here and enacting hostilities."

Silver grunts and looks at the matoran, still held still.
"And who might you be?"
The red aura Maxilos left in the air returns and a red flash follows. The matoran has now vanished. The aura hands and shortly dissipates.
"Don't leave me hanging", Silver says sarcastically.

"An armory. My master created this city with the intent to amass an army for use against interdimensional threats, and ones from this universe. His oracle has told him something is coming. Additionally, we welcome any who seek safety and lack a home. Speaking of which, if The Order needs an outpost that exists outside of the pocket dimension they are in, they are welcome to use facilities here for a time."
