Great story! The characterizations were perfect! Hearing Maglors POV during all this is a different take than what we normally see, and I really like it! I really liked the bits about Celegorm, and what felt to me as foreshadowing. The last paragraph was great, with Maglor going on as long as he must.
Overall I think the reason I liked your story so much is that you portrays Maglor as I've always imagined him. Sensible; and not as consumed by his oath as his brothers. I'll recommend your story to others!
