Death is a feature in Sims Freeplay that you unlock in the Life Dreams & Legacies Quest. The player is first introduced to this feature when they are forced to sacrifice a Sim, leaving behind a Silver Life Orb. Afterwards, all Senior Sims, once they reach the end of their life stage, will freeze in place, have an exclamation mark above their head and have a spell beneath them. If tapped, a prompt will ask whether you want to reverse their age to the beginning of their Senior life stage, or let them pass on, leaving behind an orb and lots of XP. The orbs can then be sold, passed on to another sim or used to stop aging.
