kasst

 

Grown in lab by ZOTIA Corporation.
Designed to withstand prolonged cryosleep and zero-g environment.
ZOTIA didn't use Explorer Drones - they relied on (post)human deep space surveys.
Kasst was one of only three successful attempts to create a (post)human explorer.

Over one thousand years old, including cryosleep - probably his lifespan can exceed this number even without hibernation.
Unable to perceive visible light but able to see electromagnetic waves and fields and wraiths.

'I have seen the nightmares of the Deep Void. I have seen Void itself. The Eye allowed me to look inwards and eviscerate the memories - to amputate these parts of my past that were too heavy to bear. To remove what wasn't mission-critical.'

• What is the mission? I bet it's the ZOTIA's Shadow Master who receives Kasst's reports. 
• Proton Surveyor was his ship. When it was damaged by tttttnrh, he left it and switched to something else - probably a Black Ops ship, based on a Straggler tech. The web of Old Corporations' influence is still active, even after millennium of their destruction.
• ZOTIA controlled Ares. Or he visited it during the initial part of his journey. That's where he found the Eye. Nevertheless, he must be much, much older than we think. It's said that the Corporate Wars lasted for over two centuries. And the Solar System was off-limits even before that time.
