Something has happened to the world. People are changing.
It all starts when a subject is "chosen". How that happens I'll explain later. What matters now is that time
is ticking. The next inanimate object they touch with their bare hands will make an arc of blue lightning
appear, going from the object to the subject's hand. The next time that person sleeps, they will disappear
from their bed.
Two weeks later, they will awake in the nearest forest or mountaintop. And they will be the opposite gender.
They will also have changed depending on their object. It could be a minor change in interests, or a complete
overhaul of their personality. For example, a man who touches a deck of Magic cards could just become a girl
with some interest in the game, or a complete geek. These other changes can lead to differences in mind,
weight, and muscle.
After wandering back into civilization, the subject will be scared and freaked out 100% of the time. However,
over time they will inevitably accept the change and their new personality. The time this takes could be hours
or weeks. They will remember who and what they once were, but will prefer their new body.
After they have accepted it, the next person they touch will cause an arc of red lightning, which marks that
next person as "chosen". In addition, sometimes people are "chosen" by actual red lightning from the sky.
People who have already changed cannot be "chosen" again.
The change cannot result in being older or younger than the person once was. It cannot change their species or
make them into an inanimate object.
Who shall we follow first?
