The Canari is a blue vase with three legs, which appear to haver originally been nails as they are very sharp. It has been used for a variety of magical causes. It's primary use appears to have been for the collection of blood from a sacrificial victim. It served this purpose in the series twice in the first episode. The Canari was a major prop device in the first series, although it only appeared in the first few episodes of the second series, and was later removed along with the rest of Cassie's possesions after her death.
