you found a soul rock.
Quickly, listen.
Go to where you found it, about 5 meters below where you found it, there will be a note. Read the note and follow the instructions to make it to the warehouse. After that, point your telescope you found during the voyage there and aim it at the cellphone tower approx 3.14 miles from the warehouse. Look at the very top, you should see three symbols, you will need this later.
At approx 3:14 am, sneak out of your home and go 2 paces back from where you found the stone, you will see a stone-sized indent in the bricks, place your stone there to have it identified as the real thing, if identification is a success, the door next to the indent will open, you will go in and meet the storyteller Ray. trust Ray with your life. He will take you to the Sanctum. There you will learn about your powers. Good luck.
