Transmat:Species
The 456 (pronounced 'four-five-six') was an alien race that negotiated secretly with the British government in 1965, and again in 2009. This designation was given to them by humans based on the radio wavelength they used, and they took on the name as their own in their dealings with humans rather than offering the actual name of their species, if any ever existed. As they later revealed, they were drug dealers. The 456 used children as "the hit" because the bodily chemicals they create "felt good". Very little was known about the 456's biology and anatomy, as humanity only had contact with one member of the species, who remained within a nearly opaque gas, contained within a transparent chamber. The natural design of their body consisted of three "heads", connected to one body via three long necks, possibly a conjoined triplet species. It resembled a large, plucked, three-headed swan.
