System Mastery is a both a property and podcast with two hosts, Jef and Jon. The series proper, System Mastery, revolves around Jef and Jon reading old RPG books and discussing the settings and mechanics interspersed with a liberal amount of anecdotes and tangential discussions.

According to unconfirmed reports, Jef and Jon are two separate individuals. This is commonly regarded to be a false claim however due to their indistinguishable voices on-mic. Therefore, the truth of the matter is that the podcast is actually hosted by a single man and his sock puppet.
