I am looking for concepts, creatures, objects, weapons, ... that have a link to each combination pair of these 4 mythologies: Greek, Egypt, Maya, Norse. They can be historical or mythological.
For example, for Greek+Egypt something like "Library of Alexandria" works.
- Greek+Egypt: Library of Alexandria, ..?
- Greek+Maya: ..?
- Greek+Norse: The 3 Fates, ..?
- Egypt+Maya: Pyramids, Glyphs, ..?
- Egypt+Norse: ..?
- Maya+Norse: World Tree, ..?
