H.au'u (Th.us'ūng V) is the fifth world from the sun of the Th.us'ūng system, Xi'an Empire (SaoXy'an). A dwarf planet with very low gravity, it lacks a substantial atmosphere, and conditions on its surface are nearly identical to being in the vacuum of space. It is believed that the Xi'an government utilizes the planet to conduct experiments here that are considered too hazardous to be done elsewhere in the system.
