Larstaism is a religion from Scadrial.
Sazed considers Larstaism as the truth longer than other pre-ascension religions because it has no illogical or contradictory tenets that he can find. This is because Larstaism does not focus on answering existential questions and the afterlife and thus avoids having many contradictory doctrines. Larstaism focused on "seeking the divine" through art and creation. Larsta monks were artists that were supported by the Larsta people. The Larsta left many of the descriptions of Scadrial's pre-ascension plants and animals, such as Mare's flower that Sazed uses to model new flowers from.
