*Laur was responsible for mastering and overall arrangement, and he details the three composers' contributions to each part of the song here.
*Laur mentioned in a Twitter Space that the title was supposed to be an anagram of "Arcaea End" (although in actual fact, "Arcana Eden" contains an extra "n")https://wikiwiki.jp/arcaea/Arcana%20Eden.
*The small text in the song's jacket art reads: "MARK OF SURVIVAL".
**Similarly, Pentiment's jacket reads "MARK OF SUBMISSION".
*Generating a spectrogram (see below) of Arcana Eden's audio reveals Team Grimoire's logo in the song intro.
**The part of the intro containing the logo was used in the PV for Final Verdict. This was discovered soon after the PV's release, effectively leaking Team Grimoire's involvement before Arcana Eden's artists were officially revealed.
