Also this AU looks very much like Fabletilt. Toriel swaps with Sans, Asriel with Undyne, Asgore with Papyrus... maybe this AU has two different names.
Changes Edit ==
* Asriel is the Captain of the Guard.
* Alphys is the Caretaker of the Ruins.
* Sans is the Fallen.
* Toriel is the Judge.
* Asgore is the "Ambitious" (actually the leader of the exiles who resisted Undyne's rule).
* Papyrus is the Empty One, under the name "Flowey".
* Chara is the Royal Scientist.
* Empress Undyne is the Monarch.
* Muffet is the Celebrity.
