Yuri Zavoyski

 is a character heard on the Ascension radio messages.

Story
He was an assistant to Gersch until he was transferred to launching monkeys into space, due to his alleged delays and setbacks on the Gersch Device. Yuri clearly stated his resentment over the transfer, as he claims his intellect is being wasted "blasting a bunch of monkeys into the atmosphere!" He then finds a diary pertaining to Element 115 in some boxes, which he then experimented with in secret. Possibly due to his experimenting, a child (most likely Samantha) then began to take control of his mind, driving him insane until he broke down, and agreed to something with the child, Yuri then tricks Gersch into activating the completed Device, where something drags Gersch to a black hole. Yuri then laughs in triumph, but then panics as he realizes the consequences, screaming "No!" and "What have I done?!" As Gersch was trapped by the Kassimir Mechanism, it's possible that Yuri also died when he was sucked into the Gersch Device.
