1. Violence and Misfortune: Elves are not invulnerable to physical harm. They can be killed in battle, by accidents, or through acts of violence.
2. Grief and Despair: Elves are deeply connected to the essence of Middle-earth and the fate of the world. If they experience great sorrow, grief, or despair, it can consume their spirit and eventually lead to their death. This phenomenon is known as "fading" and is considered a rare but possible cause of death for elves.
