Oh dear, I have so many lol. I would say even tie between Wit, Nightblood, and Szeth. Lift might also be in there. It's such a great series. I can't believe it took me so long to get into it!

Ah good point. Still, the similarities on Threnody are eerie enough to make me suspect Odium either voluntarily or involuntarily left investiture there. Maybe.

True, but somewhere else, [OB sort of spoiler below?] This thread discusses some of the references in Oathbringer we have to this. Also we have a WoB that indicates Odium could have purposefully left splinters too (OB Leeds Signing).

Just saying hi! I've been a huge Brandon fan for a few years now and a regular follower of theories and posts here at the 17th Shard. Finally decided to make a profile and join in the fun :D. Just finished Oathbringer and I am bursting with questions and ideas. :)b

The essay for Threnody in Arcanum Unbounded says he was grievously wounded there. I believe there is also a hint that investiture left behind by that battle affected the planet. Could be Ambition or Odium, but I am inclined to think the latter.

I would tweak this to assume they are splinters of Odium. We do know Odium has been wounded and lost a chunk of himself somewhere, likely Threnody. There also was a WoB where Brandon said we have seen a Shard purposefully leave splinters. I suspect this is what might be going on on Threnody, along with the similarity between the red eyes of the Odium-influenced Parshendi and the red eyes of the shades.
