Orbius the Watcher
a maniacal beholder
Orbius appeared suddenly before the adventurers as they were rescuing the kidnapped orphans. He demanded that they give him the boy Terrem Kharatys, so the beholder could escort him safely to the orphanage.
Orbius is clearly insane and claims that he sees everything that goes on in town, and that if any harm comes to the boy, he will hold the PCs responsible and slay them.
