This piece houses what we call an immortal walker.  An immortal walker can refer to various types of entities.  This one in particular walks among universal realms.  He is a collector of powers and abilities, all things things exotic to be exact.  I'd love to be able to tell you his name, but honestly I don't think he even has one.  He is an energetic entity that can take any form he wants, so I'm pretty sure that's why he doesn't have a name.  If we're getting technical, I'm not even sure if its a "he."  
Either way, this piece facilitates a psychic connection between the two of you so that way you can pick his "brain"... and what a brain it is.  It has multitudes of knowledge and magic to offer you.  This is a perfect piece for anyone, beginner through expert.
