Childhood Home.
Wood, ugly wallpaper, ridiculously antique furniture. Iron work laid into the windows, the doors, the fireplace grate and fancy air vents. It's a house from the early 70's, but very traditional. The antique dining table is covered in guns, empty shells, bags of rock salt, gun cleaning supplies, weather charts, and books full of strange symbols and drawings.
This is Mary's childhood home, full of warmth, family, and painful duty. She was born and raised here. This is where she learned about love.
Campbell Compound/Family Library.
This large, windowless, high-ceilinged basement looks like a fallout shelter. Books lining every wall, shelves and piles and boxes filling every available space. Shelves of guns, all kinds of knives, amulets, and various occult or seemingly random objects. Of note is a wall of photos from all through history, some extremely old, some painted portraits- the Campbell family history.
This is the library/basement of their extended family's major compound, a few hours' drive from home. All the cumulative knowledge of many centuries of hunters is collected here. Mary came here many times in her youth. This is where she learned about fear.
Makeout Point.
A beautiful, serene place just off a back country road. Moonlight, a river, a bridge towering overhead but far enough away, trees providing privacy. The vague outline of two people inside the car. As teenagers John and Mary came here all the time. She loved the peace, the quiet. The ability to pretend she had nothing to be scared of. Here he told her he loved her, and promised to take her away.
That's all you'll see 70% of the time.
Except sometimes when you shake it, it will look a little different. It's hard to tell who the tiny figures without knowing what to look for (unless you get a magnifying glass, or your eyes are just that good), but they appear to be a blond girl (woman?) cradling a man while a bald man creeps.
Or, if you're very (un)lucky, you'll see them leaned together, maybe kissing ew gross make it stop. Hard to tell.
The three are a teenage Mary, dead John, and a demon possessing her own father, offering to revive John but not her (newly murdered) parents. She took the deal ewwwww without a clue that it would be her eventual death and the start of her family's complete ruin.
Far Away.
The late Seventies threw up and this is what it looks like. Earth tones, ugly patterns, yellow kitchen appliances, cheap shag carpet, the fakest plants you've ever seen. It's a fairly small apartment, fairly cheap, and most of the furniture looks like it was either used or possibly found on a sidewalk somewhere. But it's cozy and cute. Someone (or a few someones) obviously tried to make it a home.
John promised to take Mary far away, so they went. As soon as her parents' posthumous affairs were taken care of, they got in the Impala and drove south and didn't come back for a good few years. This was their one-time home for that brief period before they came back to Kansas to get married and have a family.
Home, Sweet Home.
A very homey, very cozy, very Midwestern house straight from the early 80's. Unexciting, provincial. There's iron in the windows and the doors, but one of the lines is broken- cracked, and hasn't been patched up. A half-eaten PB&J sandwich with the crusts cut off. A
familiar little boy sits at that table in front of that sandwich, though here he looks impossibly cute. His sweet little face is turned up at something undoubtedly very interesting that you can't see.
Despite its familiarity from the Darkness broadcast, it looks nicer here. Pretty easy: this is the house she had with John and the kids, Sam and Dean.
Nursery.
Darkness, broken only by moonlight streaming through the curtains and a teddy bear nightlight. Stuffed animals, a changing table, a cute bookshelf, a chair. So adorable. So perfect. The door is open slightly, letting in a sliver of bright light from what's presumably a hallway. In the middle stands a crib. The crib is empty but the blankets are rumpled, and the bedding is marred disturbingly by a few lone puddles of blood.
This was Sam's nursery. Here, the same demon who killed her parents and made her deal came in and fed the infant Sam his own demon blood. This is where she died, pinned to the ceiling. Dripping.
