In order to prevail against their mortal and immortal foe, they marshal all the intellectual resources at their disposal to overcome Wingtip's spiritual advantage. Time is of the essence since their foe is on the brink of delivering the final coup d'état to mankind. In the end, only the wielder of Puramore possesses an advantage over humanity's ancient nemesis.
