"In a letter written by Tolkien, he stated that Eru again intervened, this time in the Third Age, causing Gollum to trip and fall into the fires of Mount Doom while still holding the One Ring, thus destroying it."

"lmao the creator of the universe nodded the bad guy off a ledge thus saving the day"

Further confirmation that Tolkien is a complete hack.
