I really like Feanor. Which is always a weird thing, because you feel like you shouldn't like him because of the whole silmaril business and the oath. But he's such a nice guy for the most part.
I'll be interested to see what happens with Maglor, as he seemed less like he wanted to move into that house and more like he was just appeasing his father.

Melkor is deliciously groin-kickable. Such a nice job here with making the reader see reason to hate him while the characters, on the whole, don't see the wickedness. And it reads smooth, too. I'm yet to have a moment where I think 'oh, come on, you buy that?' about an interaction.
Celegorm and Aredhel are cute together, too. I look forward to seeing more from them, and what happens.

Turgon makes me giggle. Both in guarding the tunnel (makes me wonder how he ends up with Ecthelion as the captain of Gondolin, heh) and in questioning Rumil. I don't know how Rumil kept a straight face through all of that. Or the "I noted a bulge in your pocket" - *snort*.

About time we saw more of this. ;)
