Chade Fallstar is a fictional character in The Realm of the Elderlings, a series of nine novels written by Robin Hobb (a pseudonym of Margaret Ogden).
In features, he is very much a Farseer (his brother Shrewd especially resembled him in later life), although, it is noted, his eyes are a surprising green (most Farseer eyes are dark). When he is first introduced, his life consists largely of a secret chamber, "good food and wine, and a weasel for a companion", and secret missions for the King.
