Devos II is a Class H planet in the Devos system. It was home to a Son'a outpost. The Dominion War Sourcebook: The Fires of Armageddon refers to the planet as Davos II. In 2375, the Son'a and Dominion reached an agreement that saw the establishment of a Ketracel-white on the planet. The Federation eventually became aware of its existence prompting the Dominion to reinforce the Son'a forces protecting the facility in case of attack.
