Curious Yellow

One of the most dangerous drugs. It's a pure gold feather. After taking it, the user is being dragged underground by yellow vines and thrown into the Curious House. This is where the user has to face their worst fears which can manifest in a solid form and harm the users. 
Desdemona is trapped in the Curious House and is attacked by the Vurt manifestation of her father, who cuts her with a razor blade leaving her bleeding. Her scars remain even after she comes down into the real world.
The Scribble is also attacked by the Father.
