Tais, inhabitant of the fictional world of post-apocalyptic zombies. Has a brother. Mutants infected with the virus, but still retaining their minds. They survive as best they can, trying not to be seen by the healthy, well aware that they will be used for experiments. They often disguise themselves among the ordinary infected, where over time they have formed their own mini-tribes.
