「永恒之地」翁法罗斯是被隐藏于深空之中的未知星域。它与外界隔绝，难以被观测或触及——寻常的星际航行难以察觉其存在，更遑论经过和到达。
「开拓」阿基维利曾行遍诸界，开疆拓野，将无数的世界连接起来。对于祂的追随者们，探索银河深处的未知边界是至关紧要的使命。借助流光忆庭的特殊技术「忆庭之镜」，星穹列车成功抵达翁法罗斯，开启「开拓」之旅，并尽可能揭明三重命途的真相。
Amphoreus, The Eternal Land is a segmentum hidden deep in the cosmos. It is severed from the outside and is difficult for anyone to detect or encounter. Standard interstellar navigation can barely perceive its existence, let alone pass through or arrive at the world itself.
Akivili the Trailblaze had traversed myriad worlds, pioneered into unknown lands, and connected countless worlds. For THEIR followers, exploring the edge of the unknown in the depths of the Cosmos is their paramount duty. Using the special technology from the Garden, "Garden of Recollection's Mirror," the Astral Express will arrive at Amphoreus for the first time to initiate their trailblazing journey and tries their best to reveal the truth behind the Three Paths.
