As shown in Rhythm of War, when the vessel of a God/shard is killed, another being can take control of the power. Taravangian becoming Odium for example (I’ve been doing audio books, so I may misspell certain names).
When talking with Jasnah, Witt/Hoid mentions that when he took his shard, he chose to not be bound by the power, so he was free to move around and do what he wanted. Hence he does not seem to have power like the Gods, but he is, in theory, immortal.
How does the process above apply to Mistborn, for instance?
Here’s what I mean (and correct me if I’m misremembering or just wrong): The Lord Ruler had chosen to keep Preservation’s power at the Well of Ascension (thus keeping Ruin trapped). The Lord Ruler, however, did not have God powers, and did not gain immortality from the shard (like Witt); his immortality was because of Feruchemy and Allomancy. Preservation’s power kept returning to well after a certain amount of time.
When Vin had the same choice at the Well, she released the power, thus freeing Ruin. Does the release of power performed by Vin equate to the release of power done by Witt/Hoid? If so, shouldn’t Vin have been immortal?
I am making the assumption that the Lord Ruler and Vin both became vessels to the Preservation’s power, which could be an incorrect assumption (since Vin doesn’t really fully do it until the final scene). And if they didn’t become vessels, then why not?
Or did Preservation have a vessel all along, but the vessel itself was trapped inside the Well with Ruin’s vessel? So Lord Ruler and Vin didn’t become vessels, but just borrow some of the power?
Just looking for some clarity. Thanks.
Edit: based on current responses, I see some of my errors. Ruin and Preservation still had vessels, so only some of his power was accessible by LR.
I also see that Wit does not hold a God shard, but a Dawnshard instead (I wish the word Shard wasn’t used to describe 3 different things lol). I’m currently finishing a second pass of Rhythm of War. Afterwards, I’ll reread Dawnshard and Wind and Truth. Where was additional info on God shards and Dawnshards explained, especially when Hoid is concerned?
