Insomnia Advisory was a new fic I found myself writing soon after finishing off the initial The Lost Changeling series. And at the snap of a finger, here I am writing a mid-quel inspired by A Test for Cozy. While it uses a similar premise of if an additional character faced their fear during the events of What Lies Beneath, this mid-quel uses Aita instead of Cozy. Side note: this story cropped up due to format constraints.
