Darkenss, Lies, and Betrayal

What promises does the One Ring make to Boromir? Implied non-con. This is an A/U. It was originally written as a one-shot, I caved to fan requests and added more chapters at a later date, however the multi-chapter version was never finished and is not compatible with 's rules. I've erred on the side of caution by using the "T" rating.
