Some quests are marked with special symbols in the upper left-hand corner of the quest window. These are story quests. The symbol shows what event or story the quest relates to.

Completing quests gives you lots of rewards:
  • Every completed quest brings you one step closer to your ultimate objective
  • Every completed quest gives you gold or useful items
  • Completing quests means you complete levels and receive stars. When you get enough stars and resources, you'll be able to upgrade locations
  • You become wiser and get experience points with each completed quest. The more experience you have, the higher your level. The higher the level, the more rewards you get, and the more features you unlock.
