Bro, even using power, European pagan myths were all about fading into history. The Wanderer, Beowulf, Ragnarok, its all about fighting a losing battle.
What Tolkien did was he turned this fatality into hope. He sanctified the pagan myths. Incorporated into the Great Tapestry.
Kind of hate Tolkien.
He took everything beautiful about Celtic & Germanic paganism, then made it uglier & used it's beauty to attack and subvert the ethnos. Telling a story about how Europeans shouldn't defend themselves with power, but just "fade away Into the west" (Ie. Die)
