Not in a roleplay fashion but from a technical aspect. I know humans have a fixed age, 80 years or so. Has any character hit that age and "died"? Is there programming to force that death by old age or does nothing come of it?
There is no programed death, honestly most players vanish before there character ever reach the age of death, unless they started off at a very high age. And Elves of course never die ^^. Lizards live 700 years plus too, none of those will die of old age.
33 ingame years we are playing Illarion now - 10 years of reallife! Some very old chars, which were created in situation of their best age or as old ones, could reach their racial limit within the lifespan of the Illarion Game (maybe humans, halflings or dwarves).
