The Unmade and the Giant Sprin

They're often referenced as things that are similar to sprin lik. In the mythica, she references them as both spirits of the void and also as t nine shadows who moved in the night. They were a specific kind of spren endowed with vast powers. So we have something kind of like a sprin. And i think when they were first talked about, i had a flash back to the giant sprin that was swimming in the bay aa way of kings. I don't know if we know a hundred % for sure yet.
