Tenian-at is the capital city and largest colony of the planetoid Tenian, orbiting around the planet Telios Prime. With a population of almost 6.7 million Telians, it is also the site of the first Tenian colony, which arrived on this moon 124 years ago. Although a large portion of the population are immigrated Telians, many living here were also born here and tend to refer to themselves as Tenians rather than Telians.
