The Magnetize (BC-349) was a Stoneship-class dual-purpose galactic survey cruiser/hospital ship under the service of the Lyran Starfleet in the early 25th century, serving the Dark Star County, unlike the first two Stoneship-class starships. This ship contained several holographic programs, like Stoneship Enterprise and Stone Trek. She was one of the ships used to capture a Klingon convoy, which comprised the IKS Jon'ka and the GHS Marianela, bringing the convoy to the Darth Mall on Xita.
