This something that has bothered me. Gjallarhorn was created in the aftermath of Twilight Gap, forged from the armor of fallen guardians by the Crux Foundary. Rise of Iron has us traveling to the region to do battle with SIVA-Enhanced Fallen and essentially do the same thing. This now creates two instances of the exact same weapon being created from (presumably) the same dead guardians at two different points in the timeline. Does this bother anyone else? Edit: Turns out we're headed to Six Fronts, not Twilight Gap. That actually makes this feel a lot worse...
