The probe arrived at a planet shrouded in vast forrests, multiple shuttle class signatures could be detected leaving the planet's surface. A huge buildup of energy of an unknown kind was detected within the planet, shockwaves and earthquakes shook it to its very core, the once gently glowing forests on the planet where pulsing with a brighter but deeper blue light than before now.
Before the probe could transmit the data,
many, many Tears in spacetime formed nearby, quickly spinning up to form into wormholes.
From within hundreds of Anhybys and ships began to emerge.

One, with a totally willing humanoid translator on-board, transmitted the following message via open comms.
"This planet now falls under quarantine sector K'Larh, Any ships entering this area of space will be destroyed immidiately. Any and all attempts to communicate with them will now be handled by us. Only beings with a awareness and psionic rating above level 'Pya will be allowed to communicate with the tree's until this planet finishes its clir'h. Thank you for your understanding.
We apologise for any inconvinience They will cause the galaxy, we will attempt to slow its progress once the reckoning begins."

Simmilarly, an onlooker emerged from a rift near Manifest's location.
It attempted to speak via telepathy to Manifest, although Anhybys psionics are VERY weak, Manifest's power and psionic receptiveness should make up for it.
(since it is telepathy, its possible Manifest could communicate back and have the onlooker understand it)
WHY!
WE SENT IT HERE TO GET RID OF IT
NOT MAKE IT WORSE!
ALL OUR WORK, ALL OUR PREPARATIONS
MADE NOTHING BY YOU!
But, there is no reason to be angry.
Its ALL over now.
But, we can slow it.
As we have in our own universe.
But... how did it reach you.
We thought it could only work when touched...
Maybe it... no... it couldnt...
The anhysbys are clearly aware of the power the planet holds.
They wanted to keep it locked away, controlled by a puppet of their own creation, such as the STE.
But, they were clearly wrong about how it works, and they now must pay the price for their misunderstanding.
It seems they are destined to fight them forever.
What they will appear as next remains to be seen.
