Aredhel of all people should know the weight of promises, but I like this spin on her end much better than the lack of justification for her death than what we get in canon.

Beautifully written! I think you have made Maeglin a very sympathetic character and I've always thought he had this capability in him.  My loyalties usually lie with Aredhel from this family but I've never attempted to write Maeglin (yet). Not thoroughly anyway. I really enjoyed reading this. :)
