I just figured out something about Shaidar Haran

[W_A]

Shaidar Haran is Narg's son. It's the only logical conclusion. Extra smart Trolloc -> Super Fade. There's just no other option.

Hmmm...Really wanted to post something I see. Thumbs up (in the Roman way)

The books up through Gathering Storm do not tell the names of Shadar Haran's trolloc parents. I doubt Towers of Midnight does either.
