The Power of Four

I was just an ordinary kid, but one day as I was walking I saw something gracefully fall in front of me. It looked like some sort of paper, but as i walked over to it it was not paper. It looked like some sort of stone tablet. As I reached down to touch it, the moment my hand set onto the tablet I instantly jerked back, my hand burning. As I looked at it, I saw a mark. The tablet started to glow and inscribed these words that I will never forget:

There are 4
One with the power of shifts
One with the power of water
One with the power of fire
One with the power of Ice
All meet up to join as one
to defeat the ones of darkness

Soon after that I met my best friends who are also apart of the Prophecy. Oceana, one with the power of water, Holt, one with the power of fire, Eliot, one with the power of ice, and I, one with the power of Shifts. We have figured out the prophecy, known the darkness. What will happen?
