Bloodstone

The bloodstones are five shards of a massive stone created by the Gods of Tyria and sealed with the blood of King Doric. They broke the stone into five pieces. Four of which represented the four schools of magic (each represents aggression, destruction, preservation, and denial), and the final piece, the Keystone, was needed to reassemble the Bloodstone. The five pieces were then tossed into the volcano, Abaddon's Mouth. Later, following an eruption, four of the pieces were spread across Tyria, while one remained on the Ring of Fire Island Chain, near the caldera.

At least two of the bloodstones are used by the White Mantle and Mursaat to sacrifice the Chosen. When slain, the Chosens' souls are channeled into the soul batteries - structures created by the mursaat to keep the Door of Komalie, and ultimately the Titans sealed away.

All three bloodstones have an environmental effect that influences when resurrection is activated or when someone is killed. Near the bloodstones, either the Curse of the Bloodstone or the Aura of the Bloodstone will appear.

Two of the three found bloodstones hold inscriptions, which are also on some doors and seals in the Bloodstone Caves. Each inscription, however, changes slightly between the three locations.
