The queens' wing is a special wing used in fighting Thread. It flies lower than the main wings. Because queen dragons cannot produce flame themselves, their riders use flamethrowers. The queens' wing's purpose is to catch any loose Thread that might've escaped the main wings before they reach the ground. During the Second Long Interval, the concept of a queens' wing had been forgotten, and tales referring to them were dismissed as "blackest heresy" in F'lar's words.
