From publisher blurb:
CHILDREN OF THE PRIME DEVELOPERS
The Krythstrask are mechano-crystal beings who hail from Au, the homeworld of the Titan Willpower. They were originally developed by a group of humanoids only referred to as the Prime Developers. Krythstrak gained sentience and eventually worked hand and hand with the Prime Developers before a mysterious event caused them to disappear, leaving behind no indication of what had occurred.
The Krythstrak formed communities within the cave systems of Au called Clustraks. It was in these caves that they perfected their Skills crystal-based artisanry The Krythstrak views the crystal as one of the purest forms of geometry. They will spend years growing and shaping crystal- like structures into intricate designs. These designs decorate their living space like house plants as well as public gardens.
Given the conductive properties of many crystals, the Krythstrak learned to use their abilities to create crystalline circuits, allowing the Krythstrak to create machines and automatons that meet the few basic requirements the Clustraks have, This leaves the Krythstrak free to work towards perfecting their gardens or to explore the greater universe for better inspiration and materials to conduct their art.
