You woke up somewhere what? Cold place. An abandoned village. Your mission was to find Grandfather and find out what happened in the Manor.
You explored the village and helped some a few people you didn't know how they are still alive but you helped them and they gave you keys to open the Manor.
You opened the door and looked around and saw some notes in each room. As you learned about everything.
You went to the basement and did some stuff to open the door and went in. The door led you to a realm..?
You explored the realm and found out that Grandpa was the one who the one who killed your mother and your father. By the story you learned you were the key to let Grandma out. You continued to explore the real it led you to the door on where grandma was locked in and you went slowly near the door and it started to open. And you heard a voice saying "huh would you look at that?" He said "it actually opened for you. I guess you really were the key." "Your finally here" he said. "I almost got tired of waiting. But you really are Micheal's kid aren't ya? I see you've got his features. So pretty." "To think you'd make it all the way here on your own." You replied "after what you did to him... How could you say his name so casually?!" You said raising your voice. "That look on your face... It seems you already know everything." "Sorry your ol' granddad couldn't accompany you on your little adventure." "I was busy preparing for your grandma's return." "And if you died along the way, I could've just picked up your corpse and brought it here." "Is that why you brought me all the way out here? To die?!" You replied. "Mhm, I was hoping the monsters would do the job." "After all, how could I bring myself to kill my only grandchild? Look at you so pretty and delicate."
