Khun Boulom descended to Earth on a huge white elephant accompanied by his two wives Nang Ek Keng and Nang Yomakara and a great number of attendants. They crossed the plain of Meuang Thaeng to Na Noi (small rice field) where they found a giant gourd plant. One of the gourds was pierced with a red hot poker and out of the black sooty hole poured a dark skinned people known as Kha or Lao Thueng (High country people), recognised as the first inhabitants of the land. Two further gourds were pierced using a chisel and from these poured lighter skinned people, the Lao people.
