A follower of the Bone-Mother must perform a ceremony (27) in which they are consumed entirely in msawhat. A circle of bone dust, a thousand corrupted spirits trapped within, must be inscribed in the stone at the bottom of a tomb. The follower steps into the circle without disturbing it, wearing a shroud tailored for them, and prays. Then, they attempt to kill themselves by any means they prefer. If the ceremony succeeds, the suicide attempt fails, and they become a grey saint. The circle is absorbed into them.

Or, they can speak the Name of the Bone-Mother. If she favors them, they become a grey saint (and a Dedicate).

To control a grey saint requires either the favor of the Bone-Mother or raw msawhat power (30+a roll vs. WIL). Summoning one can be done with similar strength or by writing their name on a piece of paper made from the skin of a mortal and burning it in a censer made of bonesilver.

To capture a grey saint and draw their power, a necromancer must be (a) more favored by the Bone-Mother than the saint (unlikely) or (b) so powerful (30) already that the grey saint is weaker than them. Then they must be able to touch the grey saint and invoke the power of their msawhat to draw that power. It is a pure struggle of power and will.
