Geomancy

Geomancer is trying to restore a broken world with a help of her golem.
After deducing that her golem is old, a geomancer decides to make a new one. She finds a recipe for a new golem in her book. Together with her golem she gathers the ingredients, until they venture onto the devastated infertile islands that make up most of the planet. With some trouble they manage to get the rest of the ingredients. All but the last one. The core of the golem that acts as its heart, enabling it to live.
