So I thought to myself, "I've been listening to this Eden guy on the radio a lot, I wonder what he looks like...*checks wiki*...Crap!"
Is this a big spoiler or is there a lot left to the main quest(s) to enjoy?

I've only had the game a few days, so maybe avoid any other spoilers.

I was just using the wiki to grasp game mechanics and I slipped up, I hope I've learned my lesson.
