A bit of rare dark magic, in which one takes a bit of their soul and hides it in an object. The soul is split by committing the greatest evil there is- murder. Very dangerous, very tricky, best not to try it unless you're willing to end up looking like Voldemort.

Tom Riddle: "I still don't quite understand how that works, though, sir."

Slughorn: "Well, you split your soul, you see, and hide part of it in an object outside the body. Then, even if one's body is attacked or destroyed, one cannot die, for part of the soul remains earthbound and undamaged. But of course, existence in such a form... few would want it, Tom, very few. Death would be preferable."

Bellatrix: "No, there are pieces of you missing!"

Voldemort: "Are you talking about my horcruxes?! Because if it wasn't for them I wouldn't even BE here right now!"
