Verum Deus is a short lived campaign created by newfags on 4chan who thought they could troll the world. Their goal was to create a fictional cult and spam social networks such as facebook, youtube, and twitter. The idea originated on /x/ then mitigated to /b/ where it was left to die.
What is Verum Deus?
I don't know I think it was another failed attempt by 4chan.
Oh, what newfags!
