Peliar Zel II was the inhabited second planet in the Peliar system. This was the homeworld for a warp-capable native species. This species had colonized the two moons, Alpha moon and Beta moon, of this planet. Peliar Zel II was a Federation member.
In the 2360s, Alpha moon's government had developed a power source by harnessing the planet's magnetic field as its source of energy. Although this caused environmental damage to Beta moon in the process, Alpha moon refused to give up its new power source. This caused conflicts between both colonies until the dispute was mediated by Ambassador Odan in 2367. (TNG: "The Host")
