Interpret as you like. Bit of randomness, really. Popped into my head just a moment ago, so enjoy or flame as it pleases you. Oh, yeah, I don't own Percy. –Ishizu

P is for the perfect I felt I had to be

E is for the emptiness, the void inside of me.

R is for the righteousness I thought I had achieved

C is what I couldn't do until I was set free

Y is the only question that I failed to ask,
And not until it was too late did I see behind the mask.
