Tyrastone

The red stone, which contains powerful energy, can be extracted by bounty hunters onto their mechanical limbs, or used for trading and payment. However, due to its rarity, people usually only use Terra stone fragments for payment. Terra stones are a scarce asset of Tyra Land, and the production rate of the entire continent is very slow. It is rumored that only trace amounts of Terra stones will condense in places where Tyra matrix grows.​
