Today begins the new Destiny event Queen’s Wrath. This will run until Monday, October 6th.
You can find the emissary where the Iron Banner was behind the bounty robot. You gain reputation from doing bounties given to you by the robot. These are a mixture of PVP and PVE related bounties that are incredibly easy to do. Once you complete a bounty, you get assigned missions, completing these will earn you legendary gear. The vendor itself has shaders, emblems, a class item and blue quality weapons that require ranks to obtain.
It looks like bounties will give out about 500 reputation a day if you do them all.
