A ruler on the fast-time planet orbited by Voyager in Blink of an Eye, who has a letter sent up by balloon asking the star in the sky to stop the ground from shaking.
Kelemane appears in the Voyager episode Blink of an Eye. Voyager becomes trapped above a planet where time passes far more quickly than in the rest of space, and its presence causes constant tremors on the surface while it shines as a new star in the sky.
By the time the inhabitants have reached something like a medieval age, the star has become a figure of legend. Kelemane, the local Protector, decides to address it directly.
He dictates a courteous letter to his old tutor, a cleric, asking the Ground Shaker why it troubles his people, and has it carried aloft by hot-air balloon. For Voyager the whole of his era passes in moments.
