Well everyone, I was going to keep this to myself, but here it goes. I was playing Destiny last night, running around in the tower, and I noticed the purple ball. So, like most people do, I started kicking it around. Then, I started kicking it around various parts of the map. And it got me thinking, why is the purple ball here? Do we just kick it around? Or is it something else, like a puzzle? As we all know, Bungie likes putting secrets in their games, so here's my theory. I believe that purple ball is a key to something in the tower. You have to kick it there and do something. I already have a specific idea on what to do with it, but hey, a smart man doesn't give away all his secrets. ; )
