Er'stacian

Er'stacians were a sentient species of humanoids with purple skin and three clawed fingers per hand. They lived on Er'stacia, a planet in Wild Space, where they divided themselves into clans based upon lineages traced back to the tidal pools of their ancestors. The clans revered a single forebear known as the Venerable One, who was represented as a massive stone known as the Megalith. Despite such universal veneration for the object, each clan believed that it should have sole possession of the statue. The situation resulted in near-perpetual clan wars during which the Er'stacians wielded a mixture of low- and high-tech weaponry, such as swords, spears, and walkers.

At some point between 22 and 19 BBY, one such Er'stacian clan war had grown so out of hand that, when word of it reached the Jedi Council on Coruscant, the Jedi feared it might result in genocide. The council sent Jedi Master Mace Windu to negotiate a peace settlement, but when the Jedi reached Er'stacia, he found that no peace was possible as long as the clans clung to the belief that only one of them could possess the Megalith. Windu was only able to halt the war by carving up the Megalith into thousands of pieces, forcing the Er'stacians to either work together to repair it or to divvy up the rubble.
