Traveler's Dye

The Traveler's Dye is a nootropic designed to allow the souls and minds of its users to wander and function in universes adjacent to the user's own.

Function
The Traveler's Dye is a liquid when inert. After being activated, whether by imbibing or through contact, it transforms into an energy state, diffusing into the consciousness or soul of a being. After being activated, the Dye temporarily unbinds the mind and soul from the body and sends into one or more adjacent universes. In this state, the user's senses and the ability to process those senses are greatly enhanced, able to both make sense of any alien laws of physics and able to properly observe those same physics in action. The Dye is greatly sought after by scientists, sorcerers and artists alike for these abilities, whether they are to decipher and a new spell or device, or as inspiration from the deeply psychedelic experiences that happen upon them.

Side Effects
The Dye on principle adapts souls and minds to function in the alien laws of physics. In cases of extreme overdose, this often leads to disastrous effects. In cases of overdose, the soul or mind may permanently be adapted to incompatible physics to that of its native universe, leading to spontaneous cessation of existence once it reentered its home. In cases where the physics are compatible but still alien, the mind or soul may find that it has been changed beyond recognition. In some cases this causes changes in the body, leading to rampant and sometimes grotesque mutation.
