A Few Good Notes

These are some notes about the history of Ashen Point that i wrote in school:
-The town was a popular tourist attraction due to its rich history of paranormal activity
-A small group of cultists came here a few mouths before the Sickness occurred, those who survived to this day blame these cultists for the death of their town and the opening of the Shadow Portal, which isolated the town from the rest of the world
-The survivors of the Sickness came to call themselves The Missing Ones
-The cultists created a hoard of Demons and monsters called The Unknown, these beasts eventually turned on the cultists and killed them all and took over the town, pushing the survivors into the forest in the northeast corner of the town
-The paranormal activity brought about what the town called "The Spirit of Ashen Point" which eventually called upon people from the outside world to come to the dimension this world in in. Kevin is chosen now.
-The Anti-Spirit wanders the town in search of sacrifices (More on this one later)
-The leader of The Unknown is the Demon for of the Kevin's biological father, and sits on top of the Disappearing Tower on Katz Street (More on this later, map of town coming soon)
-The sickness started in the Samuel Johnson Memorial Hospital
-First indication of the Sickness was observed when the animals at the Zoo were going crazy and spontaneously dropping dead in their tracks with no indication of what killed them, the animals were perfectly healthy at time of death
-The Anti-Spirit is also the executioner at the "Demon Prison" where captured survivors are sent and tortured
-To the rest of the world, Ashen Point is simply a ruined town that was destroyed by freak fires, which caused the subways and sewer systems to collapse, making this town completely uninhabitable
-The Sickness causes those who are infected to become mindless creatures who attack anything that looks appetizing (especially humans). There is no known cure (except killing them). These creatures became known by survivors as The Afflicted
-The town is centered in an entirely different dimension, caused by the Shadow Portal, thus creating two towns
The Anti-Spirit
-The Anti-Spirit is the most feared being of all the summoned Demons that wander the town
-It carries a giant axe
-Its appearance is that of a hooded man wearing the bottom of a robe, his face is covered by bandages
-Before it took its humanoid form it was the most hideous and intimidating creature
-It is the executioner of the Demon Prison located in the center of Sunate Lake
The Disappearing Tower
-Built around the Shadow Portal, it serves as the capital of all Demons
-This tower only appears when the Shadow is about to fall on the town, and the powerful Demons and monsters awaken. This Shadow comes and goes at random intervals
-The Demon Lord sits atop this Tower, which we find later in the story is the main character's father in his demon form
-Inside the tower is long narrow hallways and stairs that all meet at the High Seat in the Main Chamber
The Shadow
-It is a darkness that falls upon the town, it signifies the awakening of the powerful Demons and monsters in the town (The weaker ones and hunters wander at all times)
-The warning it the sudden appearance of the Disappearing Tower, and a few minutes later the Shadow falls

Give any advice there's a lot covered here, I'm sure there's something that could use work
