The road is seventeen meters longer than it should be. No one can explain where the extra distance came from.
Six weeks after Crown-4, Commander Arken Tares is still under investigation for destroying a strategic Atlantean system. Then an abandoned Hyperborean structure answers a signal that should never have been repeated.
A military transport disappears. A sealed shaft opens by itself. Familiar voices issue orders without valid authentication. Roads bend into places that do not exist, and doors begin connecting locations hundreds of meters apart.
Restored to field command, Arken leads Amethyst into the Crown Belt, where maps, sensors, and command channels can no longer be trusted. Their orders are simple: recover the missing, contain the anomaly, and evacuate civilians before the old system completes a pattern Atlantis still does not understand.
But Crown-4 was only the beginning.
The threat is no longer trying to enter their world. It is teaching their world to accept it.
