You move ahead with caution. As you creep closer the energy you saw before begins to glow brighter. A section the size of a doorway lights up with strange runes. A xenos language to be sure.
As that lights up, paths on the ground light up as well. The paths are the size of 10 lane highways on old terra and stretch for kilometers. You hear reports of such pathways lighting up from the other teams and strange patterns being made out from the aerial recon.
There is an audible hum now and an energy around you. Your auspex and other instruments are starting to glitch and become unreadable.
"All teams evacuate back to extraction points." The command comes from Jubal himself.
"Let us move with haste, I do not have a good feeling about this." The stormseer said.
Assuming there is no objection, Shawon will start moving at the pace that only an adeptus astartes' post-human physiology could maintain for many miles without pause.
As you move you notice that the large antennae begins to peel like a banana at its tip. Four even sides of the antenna slowly pull back and down revealing a large metal rod underneath. The ground below you shifts. Your magnetic locks keep you stable, but the journey back to the ship is arduous.
The Stormeagle is already for take off when you arrive and as soon as you step on board it takes flight. You look down and it appears that the metallic planetoid is shifting and changing shape.
Once on board the Lance of Heaven emergency klaxons are sounding off. The ship lurches forward and it is as if it is being drawn to the planet. You look out an observation window and the planetoid is imploding on itself in the middle and creating a donut-like shape. Some sort of gateway is starting to reveal itself.
You see a battlecruiser of the Alpha Legion fleet get sucked into the gateway. You brace for impact because you know, you will soon be next...
You black out, or blink you are not sure. You see the other ships of the fleet floating in space outside the window. A musky brown planet is beneath you. No sign of any metallic planetoid or gateway is visible from your position.
Shawon searches for the other stormseers on the ship, interested to gauge their thoughts on what had happened.
Shawon finds Kang Dae. "Disturbing development. We went through some xenos device and arrived in a sector of space unknown to our navigation computers or our navigators. I believe Jubal Khan and the Harrowmaster from the Alpha legion will address the situation soon."
You notice other battle brothers are beginning to go gather and walk towards the bridge. No official call for this has been given, but this seems the obvious next move for many on the ship.
