The Fritham Bundle includes the Fritham Pyramid and also the panning Mines or Frithwald.

The two are designed to work in tandem as the cavern beneath the Pyramid has a tunnel leading out that can eventually link up to that on the right side of the Mines map.

The Pyramid has recently been updated in resolution so both map sets are now available in 8K HiRes forms

Or why not consider the Lifetime membership for a one off payment of only £15, get every map that is currently on the store and all that will get added in the future. Never pay again.
