Thistle

Thistle is a fairy princess of her enchanted realm. She was taken away by a group of trolls, but was then rescued by a girl named Kate, who has kept her safe in a box ever since then. When the trolls find the key to open her box, she was taken back by the trolls along with Kate.

After the Charmed Ones find their lair, they were rescued from the trolls once and for all. Thistle, however, is killed in Necromancing the Stone, when she is captured and left to suffocate in a jar. Penny's former lover, the Necromancer then absorbs her spirit to sustain his own.

Powers
Thistle can use fairy dust to do enchanting things, such as turning people into fairies or make them inoccent again.
