The Populi or Bolmus are a race of anthropomorphic mouse people who live in the Town of Bolmus Populi, located on the back of the gentle giant, Magna. The Populi spend their lives in the city, trading with the people of Lemuria while, with help from Magna, the town moves from place to place.
- Robert - A young Bolmus with a love for business and trade. Like many Bolmus he is an exceptional trader and businessman and uses this trading know-how to give random comments on what profit he could make from selling anything he sees.
- Margaret - A rich Bolmus woman and the love of Robert's life. She however does not return his love and causes Robert to leave Bolmus Populi to join Aurora's Party.
