Kit and Wren, two new apprentices in the Sleigh Bay Staging Area, discover that the Sky Dust insulation on packages designated for Frost Hollow is failing due to the resonance cold, threatening the contents. Kit is focused on the manifest accuracy while Wren focuses on physical material integrity. They bypass official protocol by using Silas’s Original Wax Preparation, a historical thermal binder, to re-insulate the crates. This action successfully stabilizes the packages but causes a significant delay to the scheduled departure, putting them in direct conflict with the delivery timeline. As they finish, they hear an early launch whistle and a faint, high-pitched grinding sound suggesting ongoing acoustic instability in the higher structures.
