Where Did The Investiture Go?

[TheOneKEA]

During the climax, when Marasi and the other Allomancers were draining the unkeyed(?) Investiture pool in the ballroom,  where did it go once it was used?

Will it return to the Shard of Preservation because it was expended by Allomancy? Will it go somewhere else? Will it return to that spot in the ballroom after a few years?

It will return to the relevant shards through the spiritual realm.  The exact mechanics of how it works are still a bit fuzzy but assuming it was her investiture it will return to autonomy just like how the atium will return to Ruin(although Ruin and Preservation are now one).

But that’s what I’m wondering about - was it really Autonomy’s Investiture? Or was it unkeyed Investiture? Or was it Preservation’s Investiture, harvested using the new Hemalurgy technique we saw in the book?

I believe it was Autonomy's although I can't find the relevant quote.

I've always seen investiture as unkey to start with. To use a soda fountain as an analogy, you can get different flavors of soda using different syrup but all using the same carbonated water. Investiture is the carbonated water and the syrup is the shard. The drink is keyed investiture. Mistborn gets coca cola, the dor is Dr. Pepper. When it's used it's broken back down into pure investiture and returned to the pool of carbonated water. Harmony just has access to 2 nozzles/flavors and that's what makes him stronger due to investiture being infinite.
