D'ndai of Calhoun was a Xenexian male, born in 2330. He was the leader of the people of Calhoun (addressed as "the Calhoun"), and a key leader during Xenex's war for independence against the Danteri. During that conflict, D'ndai solicited assistance from the Thallonian Empire, a move that helped force the Danteri to petition the United Federation of Planets to broker a peace deal, and also made D'ndai one of the most important leaders on Xenex in the post-war period.
