Their primary source of Vis is Animal, since every year a small number of sheep are born that are entirely black. These sheep when slain, or when they expire naturally, contain Vis. Enough sheep are born to generate 2d10 animal Vis/year. The sheep are allowed to live until the are needed. After their death, they are eaten, and are quite tasty but otherwise normal.
A secondary source of Vis is in a pool between Rochehaut and Stonehollow which produces 4 Aq Vis everyone Summer solstice in the form of blue fish which do not live but move about as if alive.
Being a known and respected Inn, they have many travellers who bring them important news; including bards and the like.
