When Rad makes contact with Derrik's mind he notices the connection, while successful, odd. Upon his last sentence, as he opens up the portal home he gets a response. Not from Derrik, but from something else, much more foreboding and strong. Not only does the professor hear this being's words, he feels them and even worse an image appears of him.
A larger humanoid in opulent, pearlescent white armor that covered his entire body. An azure and gold trim throughout its make. Thought to be a cape of intricate design upon further inspection wings, 4 or more, folded to give that appearance. The helmeted figure seems to stare into Rad's soul before removing it. Revealing a silver-skinned individual with monstrous scarring. His hair much like a Horses mane, white to contrast the darker silver, piercing gold eyes against black sclera, razored teeth into a smile that could curdle milk.
" Oh? It seems the book-worm has finally gained more power? Enough to speak with the mind. He believes that this evil will spread? You have caught me in quite the good mood, wizard. I shall tell you this, the one you know as Derrik, has been chosen by me. He has been gifted with the ability to smite any evil.. and unbeknownst to him.. Immortality of sorts. Do not worry of evils' taint spreading any further than it shall.. for this one shall accomplish that which I have sought for.. eons. Now please.. Do not try to sow any doubt in this vessel, I have plans. "
The image shattering like glass, Derrik does not seem to have noticed a thing.
