Your mission in the Destiny Beta is complete. Your next adventure begins on September 9th, with the official launch of Destiny.
I found an interesting site where someone other than bungie wants to take over the world. Although this is not a good idea because they will fail when the bungie webmaster turns them into chicken feed. Anyway they have some good ideas of what not to do while after the world has been domination. their list is at http://www.eviloverlord.com/lists/overlord.html it may be good to impliment some of their ideas
