Eclipsedoll

On the day of your 18th birthday you received a doll from your weird aunt with a creepy note saying "Your now of age to take care of Eclipse, be careful with the both of you" even after reading the note you didn't care, putting Eclipse back in the box you got him in and put him under your bed.
After a bit of relaxing you hear noises in your room so you carefully walked to you room and opened the door. You saw the Eclipse doll standing on the bed looking at you, the box in front of the bed.
