「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.

在常例的「開拓」之旅中，列車組成員將乘坐安全穩定的降落艙，登陸到預定坐標點；而在變例的「開拓」之旅中，星穹列車會分離出末節車廂作為降落艙使用，並隨車廂搭載充足的維生資源，確保無名客在著陸後，能夠以車廂為安全屋展開行動。

根據列車記錄，星穹列車領航員「雞窩頭」鮑勃曾多次使用分離車廂的方式進行著陸，列車車廂的回收率僅有42.4%，而已回收車廂的返修率為100%…自那以後，分離車廂的降落方式被列車長明令禁止，僅在極少數的情況下，被作為特殊的「後備方案」使用。

In standard trailblazing expeditions, the Express Crew uses secure and stable landing pods to descend to designated coordinates. However, in exceptional trailblazing expeditions, the Astral Express detaches its last coach to serve as a landing pod. This coach is equipped with ample life-support resources, ensuring that the Nameless can use it as a safe house for operations after landing.

According to the Express records, Touslehead Bob the Astral Express Navigator frequently used the detached-coach method for landings. The recovery rate for the detached coaches was only 42.4%, and of the recovered coaches, 100% required repairs. The detached-coach landing method has been explicitly prohibited by the conductor since then, only to be used as a special backup plan in extremely rare circumstances.
