FEAR stains the forbidden ground in the cockpit too

Browse Source 
The aura's warp-walking diamond — dreadDistance ≤ 3, extracted to one
shared fearCells so the board's dashed ring, the cockpit's floor stain,
and the engine's refusal can never disagree — now tints the flagstones
violet in first person, breathing like the board's aura, beneath the
dread ring already at the bearer's feet.
