An extra foolish mortal starts to set up a shady summoning circle they found online. Not expecting it to work, they quickly make themself scarce when a young imp appears.
The short figure is dropped to the ground unceremoniously, looking around with wide eyes. Due to the incomplete ritual, she's unable to leave. With nothing else to do, she stands up, dusts herself off, and quietly begins to explore the grounds outside. She minds where she steps, not wanting to trample any graves. That would be impolite, she thinks.
Madame Leota opens her eyes. A strange tingling made her brain buzz. "What is this?" she mused quietly.
The answer came from within the mansion, drifting out of the plaster and lath, and through the wallpaper.
"It's... otherworldly? Like from another plane of existence?" It wouldn't do to ponder when there was a potential threat on the grounds. Or at least, someone else should go out and see to the threat while she did her pondering.
She turned her head to look at a board on the wall just to the left of her chair at the seance table. It was lined with bells, each with a label coordinating to a specific room. The one with Ghost Relations Department was jangled, and a coordinated bell on a board in the Ghost Relations Department, but one labeled Seance Room, tinkled in turn.
Beauregard looked up from a stack of Death Certificates. "Hrmm.." Then he reached over to a strange box contraption on his desk. It had a little horn on it, with a label reading "Spectrecom, patented by R. H. Goff," and a short row of buttons. He pressed one, and spoke into the horn. "You rang, dear?"
"Beauregard, some... thing is on the grounds, something not of this world. I'm detecting..." There was a sniff. "Brimstone."
"Do you think it's a demon?" He chuckled. "Or did Carlotta get into the old cheese again?"
"Just check it out. I'll find some demon banishing spells." There was a click.
Beauregard shrugged, smiling as he put aside his papers. It probably wasn't anything to worry about. He set off to start with the cemetery. If anything, maybe some of the graveyard ghosts had seen something.
