Dor Qasham (Celestial for "Far Sight") is a drug manufactured from the whiteleaf bush in the Shadowfell. It is a powerful hallucinogen and gives its users limited omniscience during their high, allowing them to see past, future, and present events across the world. With intense patience and discipline, users are able to “direct” their visions, causing their visions to follow a certain subject (for example, a user of Dor Qasham might focus their omniscience on a specific historical event, or on a country or person). This is an incredibly imprecise and unpredictable, even to the most "disciplined" users.
Dor Qasham appears as white crystals, similar in appearance to salt.
Grown only in the Shadowfell, Farsight is incredibly rare and expensive. It is generally smoked, though it may also be mixed into teas, coffees, and other drinks. Its taste is described as "sweeter than sweet."
