As far as I know, elves do not possess the ability to die. Our immortality is derived from the magic that sustains us, granting us a natural immunity to aging and illness. We may become injured or sick, but our bodies are designed to recover quickly from such setbacks. It is only the loss of our magic that could truly end an elf's existence, and even then, the possibility of being reborn into another elf's life is not unheard of.
