Device (Talisman)
The Union watches its resources carefully. Technocratic devices are essential in the war effort, but as with many other luxuries, there aren't enough of them to go around. Q Division and Research & Execution hoard their hypertech carefully. Even so, many ops have a personal toy or two that they keep in their own quarters. Not everthing finds its way back to the arsenal, and gifts, inventions and scavenged gear often belong to the individuals, not to groups.
Aside from the specifics noted in the "Devices" section of "The Guide to the Technocracy", chapter eight, this trait works exactly the same as the Talisman background. With this Background the item belongs to the agent, not to his Convention. Which isn't to say no one can take it from you - you simply don't have to return it at the end of the mission or petition a Supervisor to get it.
