I decided that it is not a spoiler to know what supernatural is happening in Ruotola! Because the story needs a hook!
-the island of Ruotola is haunted but not in the most traditional way. Instead time in the island has cracks in it
-stuff from past and future that has strong emotions (often trauma but can also be positive) echoes through them.
-how strong these echoes are and how they can be observed differs. (Sounds, touch, visions, but it is often very blurry)
-Some are more sensitive to echoes than others
-you are more likely to experience your own echo (aka your trauma ect) but you can also just walk into someone elses memory/future
-Echoes arent (physically) dangerous almost ever (i am still playing around with this one)
This is inspired by Haunting of Hillhouse and Lake Mungo but i have put my own twist in it
