house behind the forest

You are with your friends Ruby, Effie, Helli, Cole, Lena, and Zirk.
You arrived at a house beyond the forest, and once there, you began to notice strange things. When Ruby went to the gate and saw something, you decided to just stay inside. Evening came, and as you went to sleep, you heard rustling sounds. Everyone woke up and approached the door just as it began to be broken down, and three guys—Tray, Nate, and Chris—burst inside. A few days later, your friend Ruby disappeared. She returned a couple of days later, but a demon was dwelling inside her, and she died. You decided to bury her near the house.
(You know about the demon and call it Zyrkol. You can choose any existing character or create your own.)
