A naturally occurring brain chemical; in large concentrations it induces a feeling of calm, happiness, and satisfaction with one's place in the world. Allswell is forbidden to the avout, but been genetically engineered into much of the food consumed in Saecular society. As it takes 14 days for the full, mind-altering effects to build up, the Discipline limits Apert to ten days so that the avout are never fully affected. Erasmas realizes he is likely under the influence of Allswell during his peregrination over the Pole, when the prospect of falling into a crevasse doesn't panic him.
