Zed is a Tenno of few words and clandestine actions. It started high on the Tenno chain of command, leading the elite Sigma squadron during the Orokin's rule. This group worked as one under its strict and watchful eye against odds even its overlords considered suicidally dangerous.

Anyone that has met Zed face to face will quickly decry it as cold, hardly caring enough to cough out more than a few words before ending the discussion and leaving. This unusual approach to interpersonal relations left it with little in the way of "friends" among its peers, instead actively allowing rumors of its deeds to spread unabated. Like the Loki Prime the Orokin first suited it up with, it would rather work out of the public eye and let those with a happier facade deal with people.
