Finish an Era with a Desert Village which has 500 Village Prosperity
The hour you’re given at level 2 is incredibly generous for a development like this. Given the time it’s possible for a village to expand its borders to encompass at least 14 resouurce spots. Do the maths and that encourages an average of 21.4 resources per tile.
When in the desert your best bet is Quartz. Quartz Quartz Quartz. Placing the mineral next to itself will generate 18 wealth, a total that is easily buffed through the Rock Giant’s Noble aspect that you’ll unlock as soon as your finish the village’s first project.
If you find yourself struggling then a fine alternative is to apply Potent Noble aspects to the Quartz, upgrade it to Onyx, and apply another two Potent Noble buffs. This will generate a lot of resources even without some sort of symbiosis (which, in this case, is plants).
