Vanir and Æsir

There was never any war between Æsir and Vanir. That rubbish is misreading and later-time additions

Poor little (or long) Völuspá Edda poem has suffered misreading, misinterpretations, additions, and Christianization.
But who knows if this abuse really was a boon!  Our poems and myths perhaps escaped the fire because they are funny, and because they were adapted (a bit) to the Roman Empire named
Church, an adaption which we call (for fun) baptism.
Vanir pertain to peace, and only when there is peace do we have abundance of food for our family.
Note that peace means our inner peacefulness.
