Originally a beautiful garden planet, Tiburon became completely urbanized and polluted, so much so that the immune systems of the Tiburonese were suppressed through toxins. What's more, the planet and its system were to experience several outbreaks of plague, with the first occurring in 2107. Although much attention was devoted to eradicating these plagues, the bacterial strains mutated faster than the Tiburonese could develop cures. By 2122, the Tiburonese wore full-body anti-contamination suits from cradle to grave.
