Based on old legends, Khun Paen was handsome and very attractive to ladies.
Although, he had many wives, but still many ladies fell in love with him. Khun Paen had magical knowledge. He used magic to make himself invulnerable and unseen to enemies, to change the marching track of the enemies to become labyrinthine field, and to change leaves of the tree to become wasps to sting enemies etc.
Khun Paen is also a master in mantra or formulas with supernatural power.
They are used for such purposes as stunning enemies, transforming his body into other forms, opening locks and chains, putting everyone else to sleep, and converting sheaves of grass into invulnerable spirit warriors. Khun Phaen also uses love formulas to captivate women, and to allay the wrath of the king.
Khun Paen was also the first who created Guman Thong. He brought the dead baby from the womb of the dead Bua Klee, one of his wives, to the Temple outer area within the chanting hall where the Buddha image is placed. The Temple and its outer area are so sacred place that no mighty ghosts or spirits can enter. Based on the legend descriptions, Khun Paen was chanting some sacred mantras to invoke the spirit of Guman Thong while roasting the dead baby on the fire.
Guman Thong defended him against enemy spirits, act as spies, got for him money and transported him at speed.
