The House has ruled in fief-apparent over Caladan since 8711, when the Emperor awarded us the Siridar-Dukedom. Caladan is a planet rich in ecological resources, with forests and wide grasslands, rolling hills and pastoral plains.

Unique among its plant life is the pundi grass, which is native to Caladan; it resembles Terran wheat in height and life cycle, with a smaller, elongated grain that grows in clusters like sorghum. Domesticated varieties routinely yield 500-1 per agricultural cycle, using modern methods. Pundi rice is chaffed, then sifted (the smallest grains are used as seed), then ground into meal, or fried lightly in butter or oil, or popped inside a clay jar then boiled into mush. Pundi rice, and dishes prepared with or from it, are ubiquitous in the Caladanian diet, from sharecropper to Siridar. Every Caladan-born person is weaned on pundi mush (pempos), gorges as a child on candies made from pundi and yam-sugar (caramela), gets drunk as an adult on fermented pundi spirits (iskoinos), sops up whalemeat or cabbage-and-cheese soup with pundi bread (fomi)... the versatility of the starchy, slightly salty grain is enormous. It has been jokingly said that a Caladanian must always carry with them a pouch of pundi in case they were stranded in the wilderness, as without it they would certainly die within the week; the Caladanians present smile self-deprecatingly and nibble on their pundi cakes (pita).

Other, less essential products and industries of Caladan are: citruswood, a beautiful timber of intricate swirls and patterns, used as furniture paneling and the raw material of an almost infinite number of Caladanian crafts; whaleskin, used in apparel and musical instruments; glazed pottery, stoneware and mosaics; writing instruments; kokkinos, a prized red dye; hydroponic fertilizers and high-grade einsteinium, which provides most of the nuclear fuel used to power Caladan.

The population of Caladan is of medium density. There are about twenty cities of important size, four major spaceports and nine cosmodromes for intrasystem commerce. Roughly 12% of the planetary surface is given over to ecological reserve, and another 13% is virgin wilderness.
