I pre-ordered rise of iron about 2 days after it was announced, because I wanted the iron gjallarhorn. But when the gjallarwing was announced I wasn't sure if I'd get it, and I have looked around to see if I'd get it just for getting rise of iron but I only see it pop up when you look at the Destiny collection that has the game, both dlc 1&2, the taken King, and rise of iron. I really hope someone knows if you get the gjallarwing for just preordering rise of iron, and if you only get it for buying the collection then that's a bunch bullshit.
