This is what I think......
I put it in spoiler tags just in case there were some people who didn't want to read the teasers.
But epiphany can have two meanings:
1. The manifestation of deities on earth such as Angels appearing to mortals.
2. The sudden realization or comprehension of the essence or meaning of something.
Famous epiphanies include Archimedes' realisation of how to estimate the volume of a given mass, which inspired him to shout "Eureka!" ("I have found it!").
A tie in with teaser 1, perhaps?
