Arknights: Kal'tsit's Brother Escapes Containment

When the Doctor's meddling awakens Terra's forgotten past, an ancient android designated AMa-09 opens his eyes after millennia of slumber. Oldham finds himself alone—his creator dormant, his mother vanished, and his sister Kal'tsit lost in a world he no longer recognizes. But duty runs deeper than circuitry. As a next-generation synthetic designed to ensure humanity's survival, Oldham will pick up where his father left off: auditing the grand project's progress and correcting every deviation. In Terra's age of catastrophe, one relic of a vanished civilization will rewrite the rules.
