Blood Sorcery

Blood sorcery is the medium that operates through the bond of life itself. The spell's work is carried in the blood of a specific person — the practitioner, a target, or someone bound by lineage — and the operation lives in that bond as long as the blood does.

Its strength is binding power. By using blood, the practitioner ties the operation to the very identity of a living being; this gives blood sorcery the ability to do things no other medium can — bind across distance, persist through generations, reach through every barrier short of death.

Its weakness is the cost. Every operation extracts blood, and that blood doesn't return; over time, blood sorcery shortens the practitioner's life if used on themselves, and creates lasting bonds with anyone else's blood it uses.

When blood sorcery shines

Best when the operation needs to follow a specific living being.

  • Long-distance binding
    Operations that reach a target wherever they are.
  • Inheritance binding
    Operations that follow a bloodline through generations.
  • Identification operations
    Operations that target a specific bloodline only.
  • Healing through bond

How blood sorcery splits

Inside the medium, several styles coexist by whose blood is used.

Self-blood style

Practitioner uses their own blood.

Bond-blood style

Practitioner uses willingly given blood from a bonded individual.

Taken-blood style

Practitioner uses blood taken from a target — the most ethically charged style.

Limits of blood sorcery

Binding power comes with binding cost.

  • Self-cost
    Operations on the practitioner's own blood shorten lifespan.
  • Lasting bonds
    Operations on others create bonds that don't easily end.
  • Ethical weight
    Taken-blood operations create serious moral and social consequences.
