According to a line cut from DS9: "The Maquis, Part II", Curzon once persuaded Benjamin and Cal Hudson to play a game of dom-jot against two Zakdorns on Pelios Station. They played for seven hours, but the Zakdorn were triumphant. Curzon later revealed he had had a bet going on a Zakdorn victory.
The events of The Lives of Dax story "The Music Between the Notes" take place on Pelios Station, and relate the story of the dancer that Yedrin alludes to in "Children of Time".
According to the script for "Children of Time", the pronunciation for Pelios was "PELL-ee-ose".
