Stentrau (stone's throw in Khellakh) is a traditional Khell sport. Exactly when it began is unknown, but there are documents dated back to the 52nd millennium that give in-depth explanations of the rules. By the time the Great Lockist War occurred, there were continent-wide stentrau tournaments; it nearly died out during the war, but has since recovered. To this day, there are several national tournaments held annually.
On the surface, the sport itself appears simple: particularly strong Khellin lift large boulders and throw them as far as they can.
