The Tenno are the faction found in the Warframe universe. Each Tenno has a suit of armor called a Warframe. The combat abilities provided by Warframes are vastly superior to both the Corpus' high technology and the Grineer's vast numbers; even the most inexperienced Tenno can fight their way through hordes of basic foot soldiers alone, and teams of experienced Tenno can best even the deadliest enemy threats. The Tennos joined the Alliance of Nations for introducing the Warframes in the Allied Arsenal.
