Luther—founder of ARKS and the last Photoner—moves against Xion, seeking to absorb her omniscience. Aided by a time-traveling Xiao from an alternate universe, the player races between past and present to rescue ARKS operatives, confront Klariskrays II before her fall to Dark Falz, and stop Luther's transformation from consuming the Mothership. Every intervention reveals a deeper tangle of timelines, alternate selves, and the cost of knowing too much.
