Zygimantis Tarvydas, known as Mantis, was a pioneer aboard the Cicada when it crashed onto Proteus. He served as an EVA engineer and the colony's lead diver.
Mantis became disillusioned with the pioneer community and rebelled, intending to destroy the colony and end human existence on Proteus. Along with Chap Sovann, he destroyed the Old Habitat using explosives provided by Nahema Nakota.
Mantis died approximately 235,000 hours ago in the explosion he triggered at the Old Habitat, which also killed several others. Following this incident, he was marked as "do not print."

Mantis - "A testament to our discovery" Source: Found on a platform between the Therapy wreck and the Stairway to Heaven wreck
My name is Zygimantis Tarvydas. I am a survivor of the Mongolian Independent States, a colonist aboard the starship Cicada, and a debt slave to the Alterra Corporation. I am with my friends Rauli Isotalo, Udal Singh and Melaku Sansar. Of all the things I have seen and done...this thing is the most important.
I leave this marker as testament that we discovered the remnants of an alien civilization on this world we call Proteus. Let our names be remembered by the workers and the pioneers.
The computers call these aliens 'Axum'. Something has happened to their civilization...the survivors guard these ruins, but they have been reduced to scavengers: Tailings.
I think maybe the virus did it. Seized control of them and drove them mad, as it drives us mad. But I do not know. All I know is that I am here, with my friends, looking on the work of alien minds.
