This dark spell (incantation unknown) was used to prepare a receptacle for the placing of a fragmented piece of soul within it, thereby allowing the target to become a Horcrux, tethering the caster to the mortal world, preventing death.

Behind the scenes
- Little, if anything, was known of this spell; it was possible, however, that it would be explained either in the Harry Potter Encyclopedia, or (since the former seems to had been cancelled), on Pottermore.
- The likelihood of the incantation to this spell being revealed was very low, as Rowling said that she could not "possibly tell [us]. Some things were better left unsaid." in an interview, on 30 July 2007.
