Thanks, Lalaith.

I would love to stay, but I must not; I have had so much fun here.
Good questions.
a. I think you're right. Fastarr and Embla go their own way.
b. Again, good solution.
c. Caranthir could be construed as too haughty to bother to send word to Maedhros and Maglor? Or word could get to M & M too late?
