To echo other responders, I agree that springing Ragnarok on low-level PCs seems a little too quick. It's great to have a direction and endpoint in mind for your campaign though! But building slowly to that end, introducing hints as to what's coming as well as to Loki being their secret patron, is a better way to build emotional investment for all involved and make the ending payoff that much more satisfying.
Perhaps Loki needs the PCs to find his mask because it is currently in an area particularly enspelled to keep him away. Only a set of weapons/items can "unlock" that area and the PCs will acquire these over the course of the campaign. When it's noted that all of the items are Loki-related the PCs will deduce the quest they've stumbled on. Whoever hid/dispersed these key items after locking the mask down will not take kindly to their reassembling, however, which can introduce the campaign's main threat.
