Nikhil

If they shift pantheons, one way to do it is by Loki finding himself in strange lands governed by different gods in his quest to find the missing jotuns. The jotuns may have been held hostage by these new gods & Loki has to go to war against these gods. Kratos will ofcourse answer his sons call for aid & remaining Norse gods/Valkyries/Angraboda can be allies in this fight as they owe it jotuns to fight for their freedom. That sets the scene for Kratos to do more god killing in pursuit of justice.
