From the publisher: UNLOCK YOUR POTENTIAL! Not everything can be measured via technology. The paranormal by nature is intangible and thus can be discovered by means which also seem to be intangible. It’s time to get metaphysical! With new Cases, Pillars, Events and the all-new Psychic Deck, players can now take their investigations to the next level....and beyond. THE THREE PILLARS™: BATTERIES NOT REQUIRED expansion requires the Premiere Set to play. With 34 all new cards, you can add to your existing decks or freshen them up completely!
