Cavaleiro in Warframe is located on the Zariman. He is an arms dealer in the Endurance and was a security officer on Zariman 10-0. After players reach a certain reputation level, they can go to the Zariman to find him.
1. Parvos Granu once tried to hire Cavaleiro as his enforcer for a large sum of money, but he rejected the offer.
2. As a security officer, Cavaleiro's mission is to maintain peace and order aboard Zariman 10-0. Prior to the void jump incident, on Quinn's orders, he brutally rounded up those protesting against the prolonged and unsafe void jump and executed their leaders.
3. He was one of the few adults on board the Zariman who was not affected by the void exposure or driven mad before dying in the void jump accident. After he witnessed Hombas being killed by other crazed adults, he blew himself up and the approaching attackers with grenades.
