Reliant Immortality

"Frodo: But he was destroyed. Sauron was destroyed."

"Gandalf: No, Frodo. The spirit of Sauron endured. His life force is bound to the Ring, and the Ring survived. Sauron has returned."

― The Lord of the Rings: The Fellowship of the Ring

The power to be immortal so long as a certain object, person, etc exists. Variation of Immortality.

Also Called

Immortal Link

Capabilities

The user is immortal, their existence tied to an object, soul fragments, or even a person or concepts. So long as these things exist, the user can never die.

Applications

Variations

Associations

Absolute Immortality may even be the result of the link.

Limitations

Destruction/death of the source will either:
- Kill the user outright.
- Immortality Removal/Immortality Negation, leaving the user alive, but mortal again.
Connection Removal can sever the link between the source and the user.

The link may only protect the user's spiritual existence, and thus may end up as a disembodied spirit upon their body's death/destruction.
