「永恆之地」翁法羅斯是被隱藏於深空之中的未知星域。它與外界隔絕，難以被觀測或觸及——尋常的星際航行難以察覺其存在，更遑論經過和到達。
「開拓」阿基維利曾行遍諸界，開疆拓野，將無數的世界連接起來。對於祂的追隨者們，探索銀河深處的未知邊界是至關緊要的使命。藉助流光憶庭的特殊技術「憶庭之鏡」，星穹列車成功抵達翁法羅斯，開啟「開拓」之旅，並儘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.
