Rose Glass

Glass that is either coated or infused with the substance Polvera Rossa.

Uses
Polvera Rossa, a mysterious substance found clinging to trees in the eastern woods within The Bog is most commonly utilized as a potent narcotic hallucinogen almost exclusively by Bruce Vanlouen. The fine crimson dust also has a myriad of other uses.

In the case of Rose Glass, the dust adds new optical qualities to the glass allowing an observer to view reality differently than would otherwise be possible. The most obvious changes seem to be related to the Bog, specifically entities who have a connection to Polverra Rossa in particular, such as Hounds, The Lesser Bog Canopy Squid, The Greater Bog Canopy Squid, The Bog Woodpecker, and Bruce Vanlouen.

Entities viewed through Rose Glass vary greatly, usually appearing like larger or more grotesque versions of themselves. Many entities exhibit hound features when observed through Rose Glass, despite not bearing these traits normally. Subjects who observe entities through Rose Glass will often report that they feel as though they are being watched, or that a presence is aware of them, and will often desire to stop looking.

Notably, the sky of any scene observed through Rose Glass will always be identical to the view of the sky from a very specific point on Rim Ram mountain. This point aligns with the location of General Mara Argento's skull in the Valley of Bones towards the summit of the peak.

Rosen Mirrors
Mirrors coated in Povera Rossa exhibit slightly different qualities than transparent glass. Typically referred to as "Rosen Mirrors," these objects will only function when viewed by one person or entity at a time, and will seem completely non-reflective otherwise. Under these conditions, a Rosen Mirror will provide a reflection of an individual which seems to act of its own accord.

The reflection will, at first, make an attempt to appear as if it is an accurate mirror-image of the individual, however after several minutes pass it will abandon this attempt and begin acting on its own. The reflection will perform any number of actions, typically interacting with other items within the reflected space. After more time has passed the reflection will begin violently removing its skin. After enough skin has been removed, a new entity emerges from the body of the reflection.

Viewers have reported a number of different entities appearing, but they all share the same basic characteristics: They are much larger than the viewer, invariably bipedal and humanoid, and their skin is shiny and metallic. This new entity will not break eye contact with the viewer until they blink, look away, or someone else observes the mirror, at which point they will vanish and the mirror will either not reflect the viewer or become non-reflective.
