I’ve always wondered why the gods that are left after the “end of the world” were the ones chosen to survive.
Lif and Leifthrasir are the two humans left – Life and yearning for Life. Those cannot truly die so they continue on to repopulate the earth. That makes sense.
Mjollnir, Thor’s hammer, also remains. It is thunder and lightning so it should survive to bring those to the new world.
The daughter of the sun also survives and lights the new world. That’s fairly obviously important.
Baldr is the god of beauty, fertility, light and peace. These are all qualities that should be desired in a new and better world.
Vidar is the god of silence, strength and justice. These are also desirable qualities for a new world.
Vali is associated with justice and death. Death is a necessary part of life, therefore it shouldn’t cease to exist.
Modi and Magni are the sons of Thor and save Mjollnir. They are “Anger” and “Strength.” The two of them together embody the late Thor’s qualities. This is important because Thor was a very central figure in the religion and mythology.
Hodr is the blind god of poetry. Poetry was widely valued in Norse culture surprisingly. The runes and writing were often considered magical or could bring luck – whether good or bad.
