"Long ago, two races lived together in harmony: MONSTERS and HUMANS."

This is the replacement for "Once Upon a Time" for my new AU, JW!Altertale (more Altergeno OSTs will come hopefully soon. Despite the name, this AU is unrelated!)

I always found the Altertale set of swaps to be interesting, and am disappointed at how poorly they're executed in the original AU.

Oh also apparently kanako's motif is in this song

Swaps:
Skeletons with (goat-like) boss monsters, in general.
More specifically, the Dreemurr family swaps with the skelebros and Gaster, with Gaster swapping with Asriel, both being "lost" members of the family. Note that Gaster doesn't use the EUC appearance but rather a combination of many of Gaster's community appearances, due to his nature.
Undyne and Mettaton swap.
Alphys and Napstablook swap.
No swaps are applied to Frisk or Chara.
Snowdin swaps with Ruins/New Home. (Hence the Snowdin themes for the New Home equivalent, and thus for the opening).
Waterfall swaps with Hotland.



Leitmotifs:
Snowy
Snowdin Town (Part 1 and 2)
