Me and Mazirion are gonna do a Flashback thread in Riverfall, and will require a mathematician. Simply put, Mazirion will forge Carsten a sword, but he overcharges it, and Carsten suspects something is wrong. He will then go to a person who knows mathematics, who will explain what is wrong, and Carsten will confront Mazirion.
This will take place in Riverfall, during any season between early 507 to mid 510, whichever would fit you best
