Handopus

People make lots of assumptions about personalities of gods and most of them are wrong.  There's a concept of 'orange/blue morality' that basically refers to how someone can hold a completely different moral alignment than we are capable of truly understanding.  This little... creature here, is a spawn of Jergal.  The handopus, as it is referred to, is a divine entity who seeks to reclaim lost knowledge.  While that sounds like finding old texts and things of that nature, we're talking about a god of Knowledge.  His definition of 'lost knowledge' is quite different from ours.  To him, knowledge that is in the possession of someone it doesn't belong to is, therefor, stolen and, as a result, lost.  This creature scuttles through the aether and shadow, until it finds it's target... at which point, it will dig its hands into the skull of the offender, and pry out the knowledge that Jergal seeks returned to him.  Being creatures of magic, no physical harm is done to the target, but god does it hurt, and the mental trauma is not so easily recovered from.  The Handopi have also been known to rip wholly original ideas and thoughts from people at the behest of a jealous god, who is angry he didn't think of it first.  Needless to say, if you see one of these creatures scuttling towards you, your best bet is not to try to fight them, and just accept what comes next.  They find their quarry easier when the mind is not racing or restless.
