In the will of Crota strike in destiny in the last boss room there are some symbols on the walls. It doesn't seem like much but if you preordered the limited or ghost edition of destiny you would have received an arms and armament book. On page 38 and 39 you will find the thunder Lord an exotic heavy machine gun. In the top right of page 39 there are some symbols. Some of the symbols are on the walls of the omnigul boss room. How could they be linked ?
