Ending of Shadows of Self

[CoryP.1981]

Okay, I just finished Shadows of Self and wow, it was great. Things are getting interesting. I do have a question. Will I find out in Bands of Mourning if the unidentified metal given to Bleeder was of an origin from another planet in the Cosmere and has to do with more than just Scadrial? Or is it really from the "lost god" Trell. 

[Calderis]

Yes and no. 

You'll be given hints. You won't be given answers.

You will know enough i suppose (but not clearly) with the combination of BoM and WoB's.

Only more questions, no answers (at least not until The Lost Metal in probably 2020). There's always another secret.
