Background

Biological Immortality is the ability to live indefinitely by halting or vastly slowing the body’s natural aging process. Unlike other forms of immortality that render the user completely invulnerable to harm, Biological Immortality specifically means the user will not die of old age or suffer age-related decline. They remain in peak physical condition indefinitely, appearing exactly as they did at the moment the ability took effect.

However, this is technically not “true” immortality. While the user’s cells do not deteriorate over time, they can still be killed by external means such as injury, disease, or other lethal attacks if they do not have additional defensive powers. In many stories, beings with Biological Immortality appear unchanged for centuries or millennia, serving as living relics of the past or eternal guardians of knowledge.

This form of unaging existence is often tied to magic, supernatural heritage, or unique physiology and is a common trait of beings like elves, vampires, or deities who exist outside the normal cycle of life and death.
