Even Piell was a long-lived Lannik Jedi Master who served on the Jedi High Council during the waning days of the Galactic Republic. A native of the war-torn planet Lannik, he was taken from poverty and trained as a Jedi Knight at a young age, proving to be a fierce warrior and talented Force-user. He became a Master and was given a long-term seat on the Jedi Council, serving on the Council during the Stark Hyperspace War, the Yinchorri Uprising, and the Eriadu Trade Summit. Piell also occasionally served with the Palace Guard of his species’s prince and foiled an assassination attempt on the prince—at the cost of one of his eyes.

In 32 BBY, Piell was part of a team of Jedi sent to Malastare to conduct peace negotiations between the newest prince of Lannik, R’cardo Sooflie IX, and the Red Iaro revolutionaries, who wanted the fighting to stop. The negotiations proved fruitless, and several of Sooflie’s guardsmen—one of whom Piell had once served alongside—attempted to assassinate the Jedi to win support for the Red Iaro. Piell managed to foil the attempt and later helped save Sooflie from an attempt on his life by the remaining Red Iaro members. During Piell’s continuing service on the Council, the Corellian Jax Pavan became his Padawan learner.

When the Clone Wars broke out on Geonosis, Piell was there to fight the rising Confederacy of Independent Systems, and he served in many other battles during the war. At one point, Piell and his Republic Navy captain, Wilhuff Tarkin, were captured by the Confederacy for their discovery of the Nexus Route hyperlane. Although they and their clone troopers escaped from imprisonment in the Citadel, Piell was fatally wounded by an anooba. Before passing on, Piell sent his half of the Nexus Route intelligence to the Jedi Council through Jedi Padawan Ahsoka Tano. Piell was laid to rest on Lola Sayu, where his sacrifice could be remembered.
