GM Note:<br/><br/>The portal is a dimension door to another plane of existence, though it has a few spells cast upon it so as to conceal its true nature.  Where it leads, you do not know, though you strongly believe that it is to some pocket dimension where an item of power resides.  To look upon it and perceive it whole is to know its nature in a manner that is intimate but ineffable.<br/><br/>SOMETHING WAS HIDDEN HERE ON PURPOSE.<br/><br/>SOMETHING NEEDS TO BE FREED.<br/><br/>SOMETHING IS PROTECTED BY EVIL WITHIN.
