One of Damaya’s fellow grits at the Fulcrum, Selu is a girl whom the other grits nickname “Crack.” She is deeply unpopular and her orogeny also seems especially harsh and dangerous, as if she’s constantly on the verge of losing control. Damaya enlists her help when the other grits start bullying her, but soon it’s revealed that Crack was actually behind it all—she wanted to divert the instructors’ attention from her own struggles, and Damaya was a star student who she assumed wouldn’t be punished too harshly. It’s also suggested that Crack is addicted to alcohol, perhaps explaining the wild quality of her orogeny. After she is discovered by the instructors, Crack is taken away and never heard from or spoken of again, deepening Damaya’s distrust of the Fulcrum.
