Lifestones

The Lifestones, aptly named for each member representing an aspect of life, the Heartstone, Mindstone, and Soulstone, respectively, are a trio of living artifacts that posess great power, but individually have certain limitations on how they manifest.

Heartstone
Associated with a red hue, the heartstone is a living artifact that posesses great power, but is incapable of both thought and physical manifestation as its own entity, abilities reserved to the Mindstone and Soulstone, respectively. As such, it expresses its power through bending the will and empowering any number of minions.

At one point before his more well-known experimentations on the pets of several Ludusians, Kuipter attempted to gain control of the Heartstone along with its current collection of followers, known as the Wilhelm Assembly. Although this plan would have given Kuipter an immense upper hand against Revelian's power derived from the Will Fragment, he ultimately was unable to control the Heartstone and members of the Wilhelm Assembly, and the project was abandoned.
