The Water Margin
Death is cheap on Athas. Gladiators fight, bleed, and die for the amusement of the masses. Slaves die from heat and deprivation. Travelers die from dehydration, starvation, and the attacks of monsters and raiders.
Death can come suddenly, at any time. Players need to recognize that the struggles of Athas can sometimes be arbitrary, and sometimes death has no meaning. This is simply one of the grim features of the setting.
When your character dies, you will have a chance to transition in a backup character from your character tree. After the game session, you can make a new character, who will be one level below the level of the character who died, to a minimum of 3rd level. (Since lower-level characters gain more experience points from encounters, the new character will eventually catch up to the rest of the party.)
