A backscape of Shader Logoth or at least something tangible to the Two Rivers would've been nice. I assume I'm looking at Moraine and Lan.

The only other instance I recall of someone having prolonged exposure to a tainted blade is Talmanes, in A Memory Of Light. Granted he doesn't succumb to the blades sickness until he's on deaths door but he was pitched in battle leading the Band of the Red Hand in Mat's absence and only Nyneaves' healing barely saved him.

Tam only succumbed to his wound long after the fervor of battle had long since passed and then became delirious. This is indicative of the continuous struggle of light vs dark. As Tam had no more enemies of the dark to battle. Talmanes did,and would've succumbed to his multiple wounds faster without having a need to prevail against the dark.

Tam's fever would've been indicitave of Talmanes if Cairhien wasn't on fire at the time.
