Then look up the spell "Burden of Time" in the spell index. You should find all your answers there. In order to stop the rapid aging and death of your troops you will need to dispel the Global Enchantment, or defeat the pretender who has cast the enchantment.

Unless this changed in patch 2.06, defeating the pretender is not enough to stop a global enchantment. You must actually kill the mage that cast it, or dispel it. This can be tough to when the mage was a sauromancer that did not die, but was removed from play when the god's dominion was brought to 0.
