Sumria

The Sumrias were a sentient species hailing from the Lol system, a part of the Lol sector of the Outer Rim Territories. Members of the Sumrian thought-caste had hands with four digits, and as a result the species developed a base-eight measuring system that went on to serve as the basis for the development of Df, a parameter characterizing the combat performance of military artillery. Shortly after the Battle of Yavin, the contribution of the Sumrias to the development of Df was mentioned in a compilation of Imperial documents made by Rebel Alliance historian Major Arhul Hextrophon for Alliance Supreme Commander Mon Mothma and other Rebel officers.
