Marvo was first seen in a flashback speaking to Damaras. He tells Damaras even Vekar is incompetent and dimwitted compared to his brother Vrak, as the first born son Vekar is destined to succeed his throne. He tells Damaras that wants to serve Vekar's second in command of the Armanda, which he agrees to.
