Death

Both the body and the spark can, in a sense, die.

A body is typically considered dead when its physical, biological functions ceases to function. A spark can remain diffused in the body's skeleton, but without consciousness from a living body, it cannot easily sustain this diffusion. Without external energy, a spark will continuously resolve and leave a dead body.

A spark is dead if it is reduced in size and power to no longer function. Wind is the most common cause of this, as strong enough fluctuations can tear the spark apart. Metamutagen can also destroy a spark if it does not have a layer that naturally resists its pull.

Fae can avoid death by slowing down the age of their body and keeping their spark safe inside. They can keep their body resilient against illness indefinitely, essentially acquiring biological immortality. A dead body, however, cannot be revived by any known means. A spark can be put into a body without a spark, but the resulting fae may only resemble the former fae in some ways.
