Neo-Veridia has awakened to emotion for the first time in generations - and it is tearing itself apart.

Hale struggles to hold the fractured resistance together as new factions rise, each claiming to know the path forward for a society relearning how to feel. But when Elias returns from the digital ether with a terrifying warning -
