[Warhammer 40k] I've just discovered I'm a psyker. What's going to happen to me?

I've just been discovered as a psyker, and I'm now being held to await the black ships. 


We've all heard rumors about them, none of them good, but what actually happens once they take me? \



Edit: Let's assume I won't be fed to the emperor for a snack, what would happen if i actually got chosen to be trained?

You and all the other psykers from your planet will be packed into a cavernous, psi-shielded hold for the duration of your journey to Holy Terra. This will take weeks, months, or longer depending on the vagaries of the warp. Some of you will die along the way.

Once the black ship reaches the Palace, most of you will be fed directly into the voracious psychic maw of the Emperor. This is most likely how you personally will die.  

However, it's possible that you have the strength and focus of mind to be spared this fate. If you have the potential, you will become an Acolyte and eventually Chosen of the Astronomicon, where you will sacrifice your life energy to the psychic beacon that makes all warp travel in the Imperium possible.  

On the slim chance that you have exceptional psychic gifts, you will be trained as an Astropath or sent to the Imperial Guard or Inquisition for further training.  Your career will most likely terminate by death at the hands (or talons) of the Emperor's enemies.  

So, you have nothing to worry about! Rest assured that your noble sacrifice will serve the Empire and the Imperium of Man far better than your life ever could.
