Earlier, I don't even know how, but I noticed a certain similarity in the names of Taravangian and Tanavast. Knowing that Brandon does nothing just because, I decided to bring this here.
If Taravangian was named similar to Honor on purpose (and we do know this kind of thing happens on Roshar with names similar to the Heralds and such), then it could be that somehow someone on Roshar has let leak the name of Honor's (deceased, right? That we know of?) shardholder, than something's going on. Was it perhaps Hoid, or one of the Heralds?
Please discuss, and if there are any major flaws here, feel free to shoot it down. It's kinda baseless, so it's no big deal, just wanted to bring it to everyone's attention.
