I want to talk about the "enmity" between elves and dwarves in Tolkien's works. Please, don't read the books by skipping lines! There was no real enmity between them. There were even times of strong friendship; for example, the elven ruler Findor agreed with the dwarves on the construction of his underground city, and later received a valuable gift from them. The Noldor often befriended and exchanged knowledge with the "children of the earth." And the famous Gates of Moria were built jointly, and to pass through them, it was enough to say "friend." But, of course, there were also disagreements: once, the dwarves attacked Menegroth and killed the elven king. But there was a good reason for this – Thingol (the elven king) refused to return something that belonged to the dwarves. But all of this cannot be called "eternal enmity." And the authors who read Tolkien added this "enmity" to their works, and they mostly judge based on the incident with Thorin. The elves of Mirkwood are quite suspicious, especially of dwarves living in underground cities. And so, stories began to spread about how the dwarves once cut down the elves' favorite grove, and since then, they have been at war for the fourth millennium. Sorry if this is off-topic, I just needed to clarify these points.
