The Sun Keep is a location of interest that exists in all time periods. It is located on an island in the northeastern region of the world maps. Since it is not reachable on foot, it requires a flight-capable Epoch (or Dactyls, in 65M BC) to visit.

The Sun Keep is used to charge the Moon Stone into the Sun Stone. It also contains one Power Tab in 600 AD.
