Drahvin scanner

A Drahvin scanner was acquired by Torchwood Three. On 26 March 2005, Yvonne Hartman, hoping that the Drahvin scanner could unlock the mysterious Sphere back at Torchwood One, had Rajesh Singh temporarily imobilize the Hub via a time bubble so she could procure it unhindered. She was ultimately unable to use it, however, she lost the Drahvin scanner in a hotel fire. (AUDIO: One Rule)
