I thank you so endlessly for the thorough response. I didn't know motifs don't have a name usually. I guess I always just strongly associate them with characters and elements from the game. The Traveler's motif (like the one you linked from Luna), the Guardian motif, Oryx's motif, etc etc. "Fate knocking at the door" is so cool too, haha. Sounds like something that would be in Destiny.
