Primordial Behemoths - Rebuilding Terra is a solo role-playing game about rebuilding Terra, a region once destroyed and poisoned by humankind, and calming frenzied behemoths. You will play as one of the many Wisp of Light, a marble-sized glinting spheroid materialized from the innermost awareness of the frenzied behemoths whose only wish is for Terra to be brought back to her glory days.
