After the usual dizziness that comes with no clipping, Vain found himself in a dark room with wires haphazardly spread all around. Level 120 is a large server room and seemingly nothing else.
The only entities on level 120 are some Wire entities. The Wires seem to be normal red/green/blue frayed wires at their extremities, but if one looks closer you can see that the ends of the wires drip blood. Cutting into a wire and looking inside will reveal the fleshy interior. Each wire tendril of the Wire has autonomous control and can act like a single tentacle. As they seem to have a mind of their own they also sometimes twitch independently from everything else.
