Technical Heralurgy is not needed to make band. A. Soul bearer fills a Nicrosil with the ability to use Nicrosil metal mind. B. N mind is given to True self who stores his identity, allowing him to tap N. Mind and transfer charge to unkeyed Metal mind. C. Unkeyed is given to Metalborn who stores their investiture in yet another N metal mind. D. The new Metal mind is given back to True self, and a medalion is created

Probably not the exact opposite of Atium but similar concept. Ruin described himself as embodiment of "change", time/ageing fits as a coresponding stored attribute. Perhaps Lerasium stores "survival" or mental preservation?

Actually I was suggesting the presence of the Shardpools in Terris mountains gave the people the opportunity to harness the investitures. Similar to Elentris on Sel was built to focus and enhance the power of Devotion's Shardpool and the Aons

I would agree that Feruchemy is likely the result to the Terris people living in the vicinity of 2 shardpools. (Although my previous theory that the Terris were the first people created on Scardial, and were over-invested by the inexperienced Gods Ruin and Preservation, has never been confirmed nor denied) I think that Feruchemy was either the result of a earlier Sliver of Preservation using the WoA to help their people survive in the Mountains; or the result of the Terris consuming Atium from the Pits of Hathsin. My second idea is based on how quickly Atium dissolves in a person's stomach and the effect Lerasium has when ingested.
