The Emperor's Tomb is a monument given as a reward for completing the Wealth Task. Like all monuments, it can only be built once per game, and provides 3 population and 400 score to the city it's in.
The task is activated when you research Trade. To complete it, one must have 100 stars accumulated at once. It is not cumulative. If you complete the task, you cannot lose it. If you spend some resources before placing the Tomb, you will still be able to build your monument.
The Emperor's Tomb is almost always a pyramid, usually square-based. Kickoo's Tomb is a pile of pearls in the shape of a pyramid. Imperius and Bardur have slight modifications. While Oumaji looks like the real pyramids from Egypt, only with a tower beside it.
