Friends of Nimrodel: Tapestry of Dreams - Discussion

[Imladris]

I was reading through old posts and I came across this paragraph from post 470

Nearby stood a slender darkhaired woman, and she held goose-feathers in her hands, reaching to him, beckoning him. "Fly to me, my Dark-love; return to me. Come back to me." She held out the feathers. Amroth reached for her, for the feathers.

Is this Nimrodel? Who is Dark-love (I can only think that it is Tharonwe but that seems a bit preposterous for me to assume so)? Or...is this something to be revealed later on?

Forgive my ignorance.
