The Heart (also known as the The Burrick's Heart Ruby) is a huge gemstone; the largest ruby ever found. Although usually deep red, it may appear bluish in certain light. One of the older sentient artifacts, it possesses enough sentience to talk, via telepathy, though it is rarely heard.
It was never explained how he obtained the Burrick's Heart, but it is well noted that Clive Warwick brought it back from one of his excursions. He had it in his possession until he wasted away, entranced by its powers. It was subsequently donated by his family to Wieldstrom Museum, where it bides its time amusing itself, though the people who presume to have it in their safekeeping are unaware of its sentience and will.
