Food for Thought - could a form of Ragnarok be coming?

-A God-destroying abomination may soon be unleashed in the North (not that geographic distance matters, but think plot-distance).
-Loki is arguing with Heimdall insisting on 'fun' and being ok with calling it close.
-The Snarl has had time to prepare and stew on its hatred, it may not be so easy to rebuild a prison. In fact, if it manages to get out before Loki's prediction, the Snarl (or whatever is inside) may even 'protect the World' from the Gods to prevent the prison form being rebuilt (granted, the Snarl is a creature of chaos, so we can't predict it).
