My guess is Shallan's scene when she drew Yalb and the others surviving in WoR (or may be even when she drew Shalash) will be more helpful than Renarin's chapters.
Thank you, Argent! No eye color question or did I miss it?
No. I didn't realize it would be so hard to guess, but I admit I'm having too much fun Although I'm running out of clues that won't give away too easily who it is.
Done Also, spren are manifestation of spiritual Ideals? I admit I've missed that. Why 'ideal' and not 'idea' or am I thinking a wrong definition of the word?
I admit I tried to make it tricky and it might have ended up somewhat misleading The 'sincere' part is a hint about the organization the guide belongs to.
What I think Kal refers to is Laral's transformation into a typical lighteyed woman - when Roshone came and betrothed her to his son, Laral stopped climbing and started wearing 'proper' lighteye's dresses, doing her hair in a lighteyes fashion, etc.
