The Lengii are the native people of the island of Leng in the Jade Sea. They are the tallest known race of mankind, and some have been known to reach seven or even eight feet in height. The Lengii are a slender people known for their beauty and having skin the color of oiled teak. They have large eyes golden in color which may grant them superior vision over other races. The Lengii now live in the southern third of the isle, as the remainder is populated by people of YiTish descent. The Lengii have traditionally been ruled by god-empresses. Legends claim the empresses of old consorted with the Old Ones, gods who are said to have lived deep below the island's subterranean ruins.
Originally the Lengii were pushed back by settlers from Yi Ti who landed in the north of the island, until they only inhabited the southern third of it. However, when the settlers on Leng broke away from Yi Ti to be ruled by their own god-empresses, they apparently made common cause with the Lengii. The first god-empress of the current dynasty, Khiara the Great, was actually pure Lengii (it is unclear if the "current" dynasty is the only dynasty). Khiara took two husbands, one Lengii and one YiTish - a customary pattern followed by her daughters and their daughters in turn.
