Hello,
Please excuse if this is common knowledge already but i couldn't find a thread about this. Nor is it in the coppermind
i just finished Oathbringer again. And i think it mentions cultivations name.
I only have the audiobook version so sadly i don't know how its spelled.
In the very last chapter, the one with Hoid. It mentions a woman floating in the air that he danced with thousands of years ago.
The name is Vatwa.
I think its talking about cultivation. He is seeing her avatar.
