Loval is an inhabited planet in the Cardassian Union. In the 2370s, it was home to a civilian outpost and a small subspace relay station, as well as a top secret weapons research installation.
Prior to the late 2340s, Elim Garak undertook a mission to Loval for the Obsidian Order. (DS9 novel: A Stitch in Time)
