We have a WOB that lersium is present in mist but it is in so small amount that it can not be noticed. But with scientific advances on scardial , it is possible to separate lerasium from the mist. Although the mists are very rare after the final accession , There is still mention of two types of mists on scardial . It is much easier than tracing the bloodlines of Lord mistborn . Any thoughts on this ? Its also possible that atium is present in the other kind of mist.
