Your story had a Lord of the Rings/The Silmarillion vibe due to the names and content of the mythology. Very interesting. It could have been a bit longer but I guess that's because it was a spontaneous effort. I didn't expect the twist at the end at all - holy hell (I'm assuming things here).
So, as I understand it, that's the prequel to a story you've already written. If so, which one? It sounds interesting.
