The outermost moon of Bridgehub is of habitable temperature for humans and Guigu, though too cold for Bactarans and Vorans. This moon's orbit intersects a thin, dark planetary ring, which deposits dark material on the leading edge of the tidally locked moon. This causes that hemisphere to be slightly warmer than the rest of the moon, bring those areas into warm enough temperature ranges for farming.
Given its proximity to the warp bridges (and eventually, to Parella Station), combined with fertile soil, it soon becomes the breadbasket of the system. Human and Guigu farmers flock to the moon, seeking a new life and healthy profits selling food for all species; the moon becomes known for the strength of its Human-Guigu relations.
