The haunted houses

Some say that the valley and the row of houses in it's border are a remnant of the world that existed here before the company's foundation. I can assure you that they are wrong.
Nevertheless, this area wasn't built like many others, neither to be inhabited or to keep dangerous manifestations and unstable shards in confinement. It's unclear if it took shape of it's own by they collision of grief or death related shards—that is, if the whole area is a single ghost formed by unaccountable shards of varied natures—, or if something in the area triggered all this manifestations in the area, or if ghosts born from that material simply decided to live together here.
The latter, while easier to imagine, is the least appealing to the academics, because the other options would explain some of the unusual events in the area. There is no hope for the debate to end any time soon, since we don't have the resources to properly study it. It hasn't been mapped and it's location is not completely clear. Some crazy people take this as an invitation to do as they please here, since the Company's authority doesn't reach it. They still haven't figured out how to stay here after the reset, so is not a real problem yet.

Geography

The valley where the haunted houses are build, lay somewhere between the Mines and the river that runs through the City and the unexplored area of the forest.
The only way to find this place is following the river. I have yet to hear of someone who doesn't end up there when they do that, no matter where they start walking and for how long. At some point, always before sunset, you will hear the noises of children playing, cars that steadily carry people to their houses, and maybe some music and chatter. You may even notice the smell of coffee and or a nice meal on the stove, and see the inviting houses at your left.
Once that happens, you won't be able to go anywhere else. Some have walked until the day restarts, and they never managed to live the town behind, As it got dark, the lights of the houses became the only ones. On the other hand, those who tried to leave the houses affirm that it doesn't matter what direction you take, you will always end up in the entry of the mines.
Cartographers assume that this "town" is located between the rivers and the mountains, and maybe the only route or routes that people can survive and complete are those that end up in he mines, but it could be an environment-ghost that behaves like a labyrint.

Ecosystem

"Everything—and everyone—in this area is dead", many people say with absolute conviction.
They don't really know that. Nobody knows for sure because there hasn't been many chances to study the soil and the plants that grow in it, or to properly observe the wild fauna in the valley. That said, it is true that there is no record of a living creature found in that area.
For a while, all you can hear is the river at your back, and the pacific noises of the town. All you can see around you is dead grass. But there are trees in the horizon, as well as pasture, some sort of crop fields and a row of houses against the starry or bright blue sky. The trees have rotten fruits and no leaves. The crops have been in perpetual decay even before the company's time loop was set. The farm animals in the are either dying or already corpses. The houses' inhabitants are ghosts (and I don't say "ghost" as in "manifestations", though they are that too) and other forms of lifeless life.

Localizated phenomena

Besides being the only place where ghosts (in the traditional, "supernatural" sense of the word) and zombies are formed and slightly defying the effects of the company's time loop, this place has many ways to kill that—thankfully—don't happen anywhere else: Manifestations formed by more than one shard tend to dissipate with no apparent influence of other Shards or ghosts. Any kind of shard in the area takes shape with no apparent trigger as soon as it enters this area. Diseases evolve faster There is no way to clean and treat wounds, the more you try to prevent an infection, the sooner it festers. Some academics argue that there is something about this place that alter the normal behavior of shards, and that that is how every creature and building came to be in this part of the valley.

Tourism
Can you believe that there is people who visit the place for fun? Mostly those who don't believe in ghosts and think that it's fun to be in a magical world where those things exists, and people who comes from worlds where they think ghosts are benign. A few hope to see someone or learn something, but most of them only want to take spooky pictures.

Ecosystem Cycles

Nothing that belongs to the area is reset when the day starts over. Maybe The Granter think it doesn't matter because everything was lost or dying already, maybe there are no shards able to restore what was a ruin from the beginning.
However, we know that the area is not immune to the company's time loop, because anything and anyone that has arrived with the day, is affected by it with no issues.
Some studious say that the reason for this apparent disruption of the loop has a simple explanation: if the whole area is a single, enormous ghost, all the changes it suffers are growth, and therefore immune to the reset, which is designed to restore damage, not to vanish progress.

Climate

It's always sunny and temperature is nice but by day and by night. Sometimes there is a mild rain early in the morning or right before sunset.
