perhaps more than any other plot conclusion (or lack thereof). The AoL AS and the relationship they shared with the Da'shain Aiel was hinted at, but never truly explained in detail. Going all the way back to the prologue and Rand's fever dreams in tEotW and his visions in the Glass Columns in Rhuideen, we were shown Singing (capitalized as a Talent). And in tGH, Rand has numerous pov's that link/liken channeling to singing or music.

I can only speculate that the Dragon Aura powers were at work most of the time, (like the orchard after his epiphany on Dragonmount and the giant trees at Merrilor). However, his encounter with Tuon in Ebou Dar was apparently different, and appears to be Rand using his Singing Talent.

We really can't blame Sanderson either, since he said RJ intentionally left the Tinkers without finding their Song. I was really looking forward to seeing the land being Healed following the LB, (at least some future inference? Something! ), and the abrupt conclusion left me unfulfilled.

Too many plotlines with no payoffs is more and more my how I am remembering this series. I can't help but think about those Mirror Worlds: What might have been....
