The day after crota came out I sat in there and explored the pits (Because everyone else was trying to finish it and didn't want to venture around) after me and a few friends ran it and couldn't get past the bridge because we didn't have enough people and everyone else was to stubborn to play with 30s and 29s. so I was exploring around dying countless times and finally ran into a door, backed into and pulled out my ghost to leave because I was getting bored and heard it open, found a chest, opened it and received my gjallarhorn. oooh boy was that a pleasant surprise too.
