Stone Throw Industries was a premium producer of Greenskin seige engines. Trebuchets and cataputs were their production items, although they were experimenting with bolt throwers and goblin launchers. They converted to the era of Blood Bowl well, now producing rapid materiel deployment, single person rock throwing devices, and diversifying into a variety of insurance and gambling products. To reach a wider audience with their financial products, they rebranded in 2516 as StoneTroa™, and have become a landmark at many Blood Bowl Stadia across the lands.

In September 2521, they were proud to announce they shall be sponsoring the new Old World Rookie Rumble. Ushering in a new age of peace and prosperity, they hope to recoup some of the losses they anticipate suffering with decrease personal rock throwing devices at the stadium. The odd fan may still be able to purchase a stealthy personal rock thrower if they know the proper password from the StoneTroa™ booth, capable of reaching any point on the pitch with ease.
