Luther's EP5 research

so there's a Keyword entry for the summons Luther was trying to accomplish in EP5. From what I remember, the technique Luther is researching is not named in global--it's only referred to as a summoning--but the Material Collection uses a specific phrase, "遡行召喚 / sokō shōkan." It also explains that Luther's first summoning attempt has nothing to do with summoning an omniscient being, which is his goal in his second attempt.

I am unsure if the Fleet translation would offer more clarity on this point, but I'm working on the assumption that this information is something only mentioned in the Material Collection. So I want to be sure to present it as accurately as possible...which is hard to do when you're dependent on MT.

Anyway, from what I can tell Luther's first summons (the one that kills Hariette) is an attempt to return something to its original state, to return to a past time. There's not much else mentioned, but I'm wondering if this means Luther realized Alma tampered with Omega's flow of time and tried to correct it. 🤔


遡行召喚
【そこうしょうかん】
ルーサーが密かに行っていた魔術。時間を遡り、肉体と存在をあるべきときまで戻すことを目的とする。その到達点は原初の存在を呼び出すことだった。しかし、召喚は失敗し、そこに居合わせていたハリエットは命を落としてしまう。エフィメラによって暴走し、あらためて召喚に挑む際は【敗者】として全知存在を呼び出そうとしていた。だが、術が完成する前に主人公の手で阻止されたため、何も召喚されていない。
