" The storm has brought Ulla to the cold shelter of the northern islands, to the darkened caves and flat black pools where she remains to this day, waiting for the lonely, the ambitious, the clever, the frail, for all those willing to strike a bargain. She never waits for long. "

― Leigh Bardugo , The Language of Thorns: Midnight Tales and Dangerous Magic (Grishaverse, #0.5, 2.5, 2.6)
