Daikinis or Tall Folk are people that generally grow to 5-7 feet in height. Daikinis are said to come after other peoples like the Nelwyns or the Brownies. Nonetheless they consider themselves lords of the earth and populate many regions of Andowyne. They have developed lore and science, such as mathematics, which are mostly unknown by the Nelwyns. The Nelwyns regard them as giants.
According to "The Making of..." the word means simply "tall person" in the Nelwyn language.
