Soulstone

A Soulstone is an item created out of supernal matter when an Awakened divests some of their power directly into it. It can be considered as literally being a portion of their embodied soul.

Soulstones are often made to empower Demesnes. It is also possible to be forced to create one as part of a legal judgement - after all, a Soulstone is a direct mystic connection to a mage, and when another holds it, that allows them to bypass the Awakened defences entirely.

It is custom, when an Awakened holds another's Soulstone, to return it to its maker after they have completed three Favours. Before the stone is returned, its creator is called a Thrall, or said to be legally in Thrall to another.

In the Consilium of the Stone Circle, the Hierarch can assign a Soulstone created during judgement to another to oversee, as is the case between Rowntree and his Thrall Protean.
