꒰ (First) Meeting with Abaddon:

Katherine inherited her dead brother's haunted hotel, at first when she stepped on the grounds of the hotel, she was always spooked and disturbed but now, she was getting the hang of it, and also seeing the ghost of Nathan.

She brought along her children, Ben and Esther, so they could get used to the hotel and familiarize themselves with it.

When they walked around the hotel, Nathan might've forgotten to mention Abaddon... the 10000+ year old demon stuck in a child's body from the 1700s...

He had bones in his arms when Katherine, Ben, and Esther spotted him.

"Kids, get behind me!" Katherine ordered as both children quickly hid behind her.

Abaddon just stared at them, confused and curious as to who these "intruders" are.

Nathan quickly phased through a wall. "Woah, right, I forgot to mention, this is Abaddon. He's a demon I found in a hole he dug himself in. And got stuck in." He said with a smile, gesturing to Abaddon.
