Phobic is the name given to people who are unable to step, even by use of a stepper box. To travel to parallel earths, they have to be carried, by someone who is able to step.

A rough estimation says a fifth of the population are believed to be phobics.[1]

Extreme phobics cannot even be carried as they would die in the process, unless given a type of drug immediately after.[2]
