The Origins of the Terrorist Religion

Trellagism was being practiced on schedule before I don't know if this is all a cosmic battle of Cosmere shards like yeah but that doesn't really make any sense. Kondra are super interesting and I feel like even now like even by the end of this series we don't really get to the bottom of where this terrorist religion has come from or how it got its name. We have no real idea about what the myths arewhat the histories of any of these places are.
