A "Complete Silmarillion" in Spanish

[Aiwendil]

Ingwe is stated , of course in a 30’s text like the Lammas, that was the first to awake. I think there’s no later text contradicting.
But he also had a sister (Indis or her mother). So we can say that it cannot be possible, unless they could be brethren in the mind of Iluvatar, I like to think this second.

I may be mistaken, but I believe that Indis did not exist until well after the Lammas. So one cannot simply take the statement that Ingwe was the first to awake and the statement that he had a sister concomitantly.
