我は古の闇夜を呼ぶ

Missing, extremely new, or very obvious to obtain.

"I Call Upon _____" is a rather common phrase in the Orphic Hymns. "I Call Upon Night of Old" is a reference to II. To Night [Hyx]. Oronyx, Veil of Evernight, born of nothingness, was one of the first Titans of Amphoreus (if not the very first) and was residing in Janusopolis. The following lines from the hymn are quite reminiscent of the Time Titan: "Night [Nyx], parent goddess, source of sweet repose, from whom at first both Gods and men arose, Hear, blessed Venus [Kypris], deck'd with starry light, in sleep's deep silence dwelling Ebon night!"
