This is a branch story. I encourage everyone to start as many stories with different characters and transformations as you like. [This is mostly for animal transformations, but there’s always room for more. This is a playground of transformations and much more. Go wild!]

A laboratory in an undisclosed, secluded location runs multiple experiments. Strangely, there are no people in the facility; the lab is completely run by machines. One day, however, the lab sent letters out to random people, inviting them to work at the facility. Those who accept would be fully accommodated (e.g. medically, financially, food, lodging, etc.). The only catch is that participants must live within the hidden facility and forfeit communications to the outside world and during their contracted time of work. After participants accept the offer, they are given instructions that lead them to a helipad where they are flown to the facility.
Unknown to the new workers, they are test subjects walking straight into a trap. Whoever (or whatever) is behind this laboratory wants human test subjects for experimentation.
