When Pharaoh’s barge reaches the Temple of Osiris, his sarcophagus will be interred within a glorious pyramid, if you and your fellow Governors can complete construction in time. Each Governor has an allotment of blocks set aside for the pyramid and each block added to the pyramid will earn glory and currency called a deben. The first Governor to build all of their pyramid blocks will earn a bonus, but an incomplete pyramid will bring penalties to any Governor with unbuilt blocks at the end of the 4th season.
To assist you in your new task of pyramid building, the Priests of Osiris will accept resource donations in exchange for debens and the Pharaoh’s guard can be hired to procure a city card at any city, at any time.
