The Crystal Eyes are mystical objects that imprisoned the Phantom Beast Generals. There are eight Crystal Eyes altogether in which five were found by Dr. Silva Jennings. Three which Jellica revives and the rest of the five were given by Dr. Jennings to Casey to keep safe until the danger had passed.It is safe to say after the star allignment (which only happens every thousand years that revives the ancient Phantom Beast Generals.) passed away until the next thousand years that the five current eyes that still imprisoned the other Phantom Beasts are returned to Dr Jennings so she could keep studying them and put them in a museum as a new attraction after gaining more answers towards there mysterious past.
