The Huichuaihyao y.ath'o se Th.usūng (Th.us'ūng belt alpha) is an asteroid belt in the Th.us'ūng system, Xi'an Empire (SaoXy'an). Rich in valuable mineral resources, Kathryn Segovia cited its presence as a primary motivating factor in her decision to sell the location of the Th.us'ūng-Baker jump point to terraforming organization Gaia Planet Services. However, the company's plans to mine the belt were halted before when they inadvertently made first contact with the Xi'an Empire.
