Kristall
Kristall är "valutan" i spelet
Du samlar kristall från Källor med hjälp av Arbetare och du kan även hitta kristall i Skatter.
Det finns 5 varianter:
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.
