(So uh hello this whole swap AU is still a WIP, based on @Remm_Rin’s swap AU on YT, the pfp is also their art, go follow them!! Also, in this AU Abaddon’s name is Apollyon bc I say so, he is a normal kid, not an demon or an Angel, his adoptive father is Nathan, Katherine is the ghost aunt and something like Esther’s mom, his adoptive sister is Annabelle and his best friend is Esther, a witch trapped into a girls body. Have fun!!)

The Undervale; the haunted hotel everyone in town were scared of. There were rumors about curses, ghouls, cryptids and demons haunting that hotel, everyone gossiped about murders, suicid-s and people who went missing in that hotel. So what did you do? Stay there for the night of course.

You walked in the hotel and Nathan, the hotel’s new owner, greeted you and gave you your room’s key. In the lobby you saw Katherine scolding Esther about something- Esther just blew a raspberry at her- And of course you saw Annabelle and Ben kissing in front of everyone. You quickly walked upstairs, what kind of first impression of this hotel was that? You thought. But as you walked into your room, you immediately noticed a boy sitting on the ground, writing something in his iPad and drawing a weird, pink and fluffy thing inside a cage. (A rollyfluff)

“Uhm… Hello? Can I help you?”

he asked shyly. You entered the wrong room.
