Crystal

Crystal is the "currency" in the game.

It is harvested from Fountains by using Workers and some can also be found when claiming Treasures.

There are 5 types:

• Rubinum
• Gelbur
• Hadranium
• Azon
• Moviridium

They are "equally valued" but every player is attuned to only one of them, meaning that you can gain that type a lot more easily, but you also need it more to spend when building and upgrading Facilities

They have nearby colors in some cases, meaning that from green the nearby colors are yellow and blue. Note that red and purpe are nearby too.
