Not much, hopefully.

You step down the rickety old ladder and look around the massive mansion. Everything appears to be just as before... You take a few minutes to explore the upper level, but you can't spot any differences in your home now that the demons from the book have been released. Even your own room remains unchanged.

However, you hear none of the sounds usual to the building's daily life and nervous, you step into the kitchen only to realize that there's no one in it. Not even an hour ago your mother was nagging at you to clean the attic since they were tied up down at the kitchen preparing its renovation, but now there's no one here. All the measuring tapes, construction plans and other necessary tools are left discarded around the room on the counters.

"Shit," you mutter with mounting dread. Have the demons taken your family before you even realized it? Frantically, you search the other areas of the mansion. It's completely empty, but you luckily find one clue on the dining room's table, a letter from the looks of it. You traverse the steps and head over to pick it up.

Son, I've managed to get away from the initial but the others are in captivity. They know we are a part of the Order. You need to press the sigil at the bottom of the paper and teleport to the Order's keep, there you can find allies and help kill the Old Gods for good.

Your mom's handwriting is rushed but unmistakably hers and a cold panic settles in your stomach as you think about all the horrible things they would do to your family. You look down at the glowing sigil - it's the image of two extended angelic wings with a flaming sword pointed downwards. The kind of symbol you'd expect from an organization bent on protecting the world from demons.

With some trepidation, you press the sigil with your index finger and the symbol gleams brightly with a dark glow. The world melts all around you and begins to whirl rapidly as some strange magic takes hold of you. The liquid images blur into each other and create what your mind can only describe as a kaleidoscope of jumbled senses, which dizzies you. The spinning gets faster and faster but before you can pass out, you disappear in burst of light from your home and reappear at your destination, landing ass first on a hard marble floor with a pained huff.
