Everyone in the Silmarillion dies, except for Galadriel, and Sauron (sort of), and maybe Maglor, but nobody knows.
Here I present to you my guide to the characters, storylines, and other tidbits you probably forgot about because the Silm is so packed with information that it's hard to remember who's who.
This isn't just any guide, though. It's an opinionated guide.
Go on; read it and weep.
With laughter, I hope, and not in frustration at my terrible jokes and dry sense of humor.
Cheers!
