T is for Telesensorium
The telesensorium is predominantly used by scholars who wish to research certain dangerous locations, creatures or magickal phenomena without actually running the risk of bodily harm. To this end they hire adventurers looking to make some extra money: by mentally merging with them, they can access the full range of the host's sensory perceptions (but not his or her memories or thoughts) as if they were there in person. Furthermore, the joint mind can relay thoughts to the host mind, though this communication is only one way; nor can the joint mind issue direct commands to the host body. After the psychic transfer is complete, the host participant, now carrying the two minds, leaves the telesensorium to perform whatever tasks are required of him, while the unconscious body of the other remains submerged in the pool, its biological needs attended to by apprentices of the college.
