Not really a theory, but havent seen it disscussed alot.
As we progress the cosmere our characters are beginning to understand the importance of Intent, and ive been trying to think of what role Vasher will play in stormlight.
I would argue that the best use of Intent we have seen is Vasher telling his cloak to protect him. That is such a loose term open to interpetation, that it really needs 100% control over your Intent.
Soo im hoping we will see Vasher not as a swordmaster, but as a teacher of Intent.
Thoughts?
