The Lion man of the Hohlenstein Stadel

Origin
This roughly foot-tall statue, carved from ivory and presumed to have been created some 40,000 years ago, was found in the Stadel-Hohle im Holenstein, in the Lonetal (lone valley, translated), in the Swabian Alps in Germany in 1939. One of the oldest statues in existence, it is not known what this figure is supposed to represent - an anthropomorphic representation of a cave lion or perhaps a deity - or even if the statue is a Lion 'man' at all. However, it is one of the oldest statues to date and one of the first documented cases of zoomorphism, or an animal shaped form.

This inspired the Disney animated movie “Robin Hood”.

Effects
Perhaps knowing this, or because of it's connection to an unknown deity, this artifact, when physically touched, will render the user into a human-animal hybrid. The animals the people transform into, albeit not completely, seems to reside in their personality. Interestingly, the artifact has an opposite affect on animals - if touched by a creature other than human an animal/human hybrid will occur.

The artifact is neutralized by slicing into the left arm of the afflicted seven times, being more or less transverse in cuts, to match the statue. Should the artifact not be neutralized in a timely manner, the afflicted with transform completely into the form they had been combined with - embarrassingly, this artifact is often accredited for the George Langelaan's science fiction phenomena, The Fly, which simply isn't true - the disintegrator-reintegrators are stored in the Warehouse, after all.
