Not sure if anyone has mentioned this but the name, Eshonai, was a chapter in The Way of Kings.

I just noticed this adn I'm not sure if it has been addressed before but I'm rereading Warbreaker and I noticed that the letter Sash pops up, page 214, Siri tells the God King that this is "the letter sash." The same letter is used in The Way of Kings as a glyph, which implies that the alphabet or something are shared between Warbreaker (forgot the planet's name) and Roshar. Just something I noticed, I'm still pondering the implications but I feel like it's important.
