You are out on the Fractured Fields hunting for gems.

Gems out here get infused with "windshine" from the eternal winds always blowing across the fields.

Infused gems can be used for "glowcasting" ~ a magical ability to transmute materials ~ and are thus extremely valuable.

The 10 Kingdoms of Mara Pakaru that surround the fractured fields compete on collecting the largest amount of gems.

Each field you come across has a 40% chance of holding a gem deposit. For each field with a gem deposit there is a 40% chance of finding a gem. Gems increase in rarity depending on how many sides they have.

The most rare of the gems are the gem-hearts. Only 1/100 gems are gem-hearts. Gem-hearts are said to contain parts of the heart of the field-god himself, and are infused with a astonishing amount for windshine.

Which Kingdom will you join?
How many gems will you collect?
And who will strike it big and dig up a gem-heart?
