The radio igloo and temporal loops
For Leif's sensory injuries, see The Three Injuries. For recursive spatial mechanics, see The Cycle Turns Inward.
The radio igloo appears in Chapter 4 as a seemingly marginal location—corrugated metal and tuned frequencies in the red interior—but functions as the narrative's most direct engagement with temporal recursion. Canonically, Leif's doubled vision (one of three injuries) is "corrected" when Katita and Leif raise the igloo's frequency to a pitch the data-harvesters cannot parse.
Yet fan theorists and adaptation-makers read a second register: raising the frequency reverses or suspends temporal flow. This reading gains support from The Recurrence Clinic (film) (2017), which stages the igloo's interior as recursive identical rooms; and Null Station (2013), where players discover that exiting the igloo resets prior-turn memory.
The igloo's earth-drone baseline and the spine's high D/G resonance create a frequency pair some theorists link directly to the glitch—a seam unhealable because it operates across two incommensurable temporal registers. The Karman Transmission treats this directly: the igloo is the only space where the cycle's seam becomes briefly audible and thus potentially repairable.
