I'm looking for some concepts (could be objects, weapons, creatures, traditions, ...) that are common between both Egypt and Norse mythology/folklore or history/civilization.
Context: I'm working on a prototype for a card game where Gods from Greek, Egypt, Maya or Norse mythology battle each other. There are a lot of distinct Greek, Egypt, Maya and Norse cards in the game. Now I'm trying to add some cards to the game that belong to each possible combination pair of these 4 mythologies. For example, for Greek+Norse I have "The 3 Fates". For Egypt+Maya I have "Death Mask". For Maya+Norse I have "World Tree", etc... But I'm really struggling to find something that works for Egypt+Norse.
