Orbs are left behind after a Sim who's completed their Life Dreams has died. Once you have picked up an orb, you can choose to either sell it, pass it on to another Sim to upgrade it, or to build a place.
Selling Orbs Edit
Each orb has a different value, depending on how upgraded it is. Bronze Orbs sell for 40,000 Simoleons, Silver Orbs sell for 90,000 Simoleons, Gold Orbs sell for 180,000 Simoleons, and Platinum Orbs sell for 300,000 Simoleons!
