The TARDIS appeared in an underground city, with large steel buildings and many residents. People were rushing about completely ignoring the blue box that appeared before them. The doctor stepped out followed by team RWBY. "Welcome to underground Veil" The doctor stated as the girls took in their surroundings. The Doctor led them around the city and through some shops when he noticed something. Something small and silver. Before anyone else noticed it or the small silver rat saw him he walked over to it and deactivated it with his sonic screwdriver. He made sure to remove the controlling circuits from it before putting it in his pocket, and walking back to team RWBY in the street. He said in a quiet tone so nobody but they could hear him

"There's something off about this. While looking around I found a cyberat stealing power from the local grid. There are probably cybermen nearby."

Blake asked "What's a cyberman?"

He responded with "Cybermen are metal men. They have no emotion, no love, no fear, and one goal: to make everyone like them. They are ruthless in their goal and will stop at nothing to make it complete. They will kill anyone who resists and they are probably near here. Most likely hiding and waiting for the time to strike in one of the abandon tunnels."

Before anyone had time to respond a large explosion rocked the building.

"They are attacking, follow me!" He yelled over the explosion and started running down the road as people panicked and ran towards him trying to get to the main city to escape. Team RWBY had no choice but to keep up with him as he picked up things from carts as he ran. He took a scroll, a small plastic bowl, a coil of wire, and a small metal rod from one of the carts decorations. They could see the cybermen down alleyways as they ran towards the center of the cavern and what appeared to be the town hall. The building was made of white marble with a green roof and had a flag on the top of the tower, even though there was no wind. The doctor was assembling something with the parts he had taken as he ran up to the top of the building. He stopped once he reached the top and turned it on. He used it to contact the cyberman leader.

"Hello cyber leader. Recognize me?" He said with an irritated tone.

The metal man replied "You are the doctor."

"Yeah I am, and if you don't stop your attack I will have to destroy your forces." He said.

"You cannot win. It is already too late. The humans are being converted as we speak. Our numbers will only grow. You cannot destroy us!" The cyber leader said in his emotionless tone.

The doctor replied "It's not too late. It never is. Though I cannot save those you already converted I can stop you from converting the rest!" He said as he ended the connection. He began waving the sonic at it and it responded with a high pitched beeping noise.

"It's working" he said as he made some final adjustments, before climbing to the highest point on the domed roof. "I warned you" he said to the cyber leader even though he knew he wouldn't be heard by anyone. He warned Blake "cover your ears" because of the amplitude of the sound produced would only be heard by her and may damage her hearing, before activating the device. It didn't appear to do anything to anyone except Blake who appeared very annoyed. Soon they could see the explosions in the city stopping, and there was an eerie quiet. Then the Doctor spoke up. "The sound wave produced by that was able to resonate through the cavern because of its dome shape, this changed the frequency to be able to destroy the cybermen's emotional inhibiters making them self- destruct. They have an automatic self- destruct mechanism attached to it so if it were to be destroyed the cyberman would deactivate itself and explode after a few minutes. We should leave before we are seen."

Ruby asked "What about the people? Will they be alright?"

He replied "Yes the remaining survivors will go to Veil and seal off this area, believing these cybermen were creatures of grimm."

The five walked back to the TARDIS and it disappeared with nobody noticing, similar to how it appeared.
