EDIT: I redid the post to involve the Daemon thought speak. sorry for not noticing it at first.
Illyrian had been walking for while now, and Vre had remained silent. Suddenly, the walls began to echo conversation. I sounded like...Orc?!? What was an orc doing here? At least it appeared to only be one. Hopefully They could take him on. But before he could start moving towards the direction where the monologue was coming from, Illyrian heard a voice inside his head.
"Hello?"
At first glance, a normal thought. But thanks to intensive anti-psyker training, Illyrian could tell this was no friendly. The alterior motive of daemonic hatred was obvious. After a moment of hesitation, Illyrian replied. Risky, but he couldn't hold back.
Foul creature, I will spill your filthy blood and dismember you when I find you. You defiled this place, and now it must be purged of your taint.
Illyrian quickly shut his mind off from all further communication in order to prevent the daemon from entering his mind.
