In a world where the impossible becomes law, an immigration notice arrives with redacted dates and locations. Applicants must master the enigmatic Corner Law, understand the nature of anomalies and monsters that lurk beyond the veil, and demonstrate scholarly knowledge of forbidden literature. Only the physically and mentally sound—those without contagion or psychological fracture—may apply. Every immigrant must bring a trade: construction, healing, combat, or something yet unnamed. Families ascend the priority list, their bonds deemed humanity's greatest asset. This is the threshold between worlds, where ordinary people make extraordinary choices to reshape civilization itself. Acceptance means inscribing your name into the eternal records of human survival. Will you answer the call?
