Stone of Castambre

The Stone of Castambre is truely an enigma. Standing on the Isle of Fire in Britannia, it is a bleeding stone, and which a tree grows. The Stone can be "milked" for blood or strange hearts. Both of these items are needed in the act of Golem creation or reconstruction. Otherwise, there isn't really much known about the stone, apart from a book on the Isle of Fire.

The Stone played a major role in Ultima VII, where it was needed to heal the two Golems on the Isle of Love, Adjar and Bollux in the Test of Love.
