Bajor at Peace was a piece of art created by a woman called Acto Viri who was from the Wyntara Mas Province on Bajor. It was a space-scape of Bajor and its five moons, painted in short, narrow strokes on a large canvas, measuring approximately 100 x 150 cm.
It was for sale, along with some of Acto's other work, during an art festival held by the Promenade Merchants' Association in April 2376. Kira Nerys was taken by this piece, finding it very impressive, and even noticed a slight hint of blue in the upper left corner that, though it seemed to be a mistake, she knew was the Celestial Temple. She eventually bought the painting in May and hung it from the outer bulkhead in her office. (DS9 - Mission Gamma novel: Twilight)
Kira gave the painting to Ro Laren when Ro became the commanding officer of Deep Space 9. (ST - Typhon Pact novel: Plagues of Night)
