The Isle of Mordol: Background: The pyramid

Anyone inside the pyramid does not age, need food, or need drink.

At the bottom is a pool; people looking into it can see the future, past, and/or present. There is no controlling it. There is a 45% chance it will show someone an important event, not more than once a week, and -5% each successive week they try; +5% each week they don’t look, not going higher than 45%.
