Something strange that I've been thinking about post RoW. When Odium pulled Taravangian into his spirit vision at the end, Nightblood also manifested into the vision along with him. I've re read it multiple times and Taravangian was not holding onto the sword in anyway before he was pulled in. But it manifested there anyways. It says Odium was also surprised to see it.
So if Szeth happened to be carrying a Honor blade or an unbounded dead shardblade at that time, would that also have been manifested in Odiums spirit vision place ?.
Or is this something due to the special nature of Night blood.
What do you guys think ?
