I've completed the RoI campaign, but it still says I haven't completed it. The quest allows you to start the Gjallarhorn quest, which I've already completed, so I dunno what the issue is. I've tried abandoning the quest and grabbing it from the Kiosk, I've tried beating every RoI mission on both normal and hard difficulties, everything. Nothing has worked.

Did you try speaking to the Cryptarch at the Iron Temple? Either that or speak to Saladin to start the quest.
