As the mechanical walls rose up crushing hezrou and retrievers alike and slamming those close to it away. The tanar'ri had to figure out another way inside the city. Unfortunate for Lithium it did not take long. Remaining retrievers and hezrou moved to the main gates. Once they reached the main gates they just stood there waiting for something. More Tanar'ri joined them as well, Dretch, Quasits, Nalpashnee,Glabrezu, Babeu, and even a few Succubi. But in the end they just waited as if something was coming or perhaps not. The Glabrezu only waited for everyone to be present at the gates and once that happened they vanished reappearing inside the gate houses. From here they began using their telekinetic powers to turn the gears and levers which began to open the gates. Waiting for the knights at those gates were legions of demons. Only now there was no escape. If that did not make matters worse the storm turned into a storm of fire which came down doing damage to the buildings.

Ishmael saw the mechanic walls shoot up giving him and the knights a bit of an edge against the remaining demons on the walls and those within the city. His back was saved earlier by someone. She used black pedals sharp enough to cut up the retriever. He took the time to turn and see the group below who had moved to his aid. Perhaps one of them was the owner of those pedals. He made way towards the stairs to meet them. As he reached te stairs knights started rush past him. "The gates have been breached,... We have been given the order to hold off the demons and help evacuate. There is only one way of escape right now... The sewers, get to the sewers. We are abandoning the city." They told him. He couldn't believe what he was hearing but he understood it. He continued down the stairs as the fire began coming down destroying homes and shops. When he reached the city floor he spent little time to reach the group. He noticed that there was only three elves left, and with them was a samurai, a witch, a rogue, and some young girl with a staff. 

 "We are abandoning the city, it is lost. As we speak demons are entering the city from the gates. They managed to open them some how and the only way out is the sewers. There is a entrance to it close by in the market."

 Cassandra was already at those such sewers helping those people who were locked in their shops out and into the stinky sewers. She did not know the full situation but she felt it was her job to help as many as she can.
