Death

If HP is reduced to 0 or less, damage is subtracted from Strength
Afterward, a Strength check must be made
If succeeded, the character perseveres
If failed, the character is dying
They can no longer take actions
They lose 1 point of Strength at the end of each round
Any additional damage is subtracted from Strength
If their Strength reaches 0, they are dead

A player should immediately make a new character.
This new character should enter the next scene as expediently as possible, in whatever way makes even a small amount of sense.
You are encouraged to disregard any need for realism in this case.
