Is there a reason why "Excalibur" (Hollow Ataraxia) and "Everything is On Her Hand" (EXTRA) share a motif? Do any other Fate tracks use the motif?


Specifically, this one:

It appears at roughly 1:03 in the Hollow Ataraxia track (immediately following
the section that FGO uses as regular Saber Altria's NP BGM), and at 0:33 in
the EXTRA track. NUMBER 201 don't normally seem to reuse motifs unless the
tracks are related in some way, so I wondered if there's some connection I'm
missing? (Even one as small as "the song appeared in promotional material back
when they were trying to convince everyone Nero was actually Altria.")
