After being freed, Tom and Hester talk with the Captain, Peavey, about his plans. He wants to go to the recently destroyed Airhaven (because of Shrike) and loot it. The problem is that Airhaven is on an island. They try to go across the water on the town and it gets destroyed and sinks.
Tom, Hester, Peavey, and some of the other crew mates escape the sinking town and go to land. Peavey falls into quicksand and his crew mates shoot him to try to become the next captain. The crew mates then look to shoot Tom and Hester but are interrupted by none other than Shrike, back from the presumed dead.
Katherine sneaks into the engineer guild to spy on the MEDUSA plans. She finds out that MEDUSA is to be tested soon and wait to see what happens.
Shrike slaughters the crew members and then heads for Hester. Tom heroically stabs Shrike in the back before he gets Hester. She has mixed reactions because she had a past with him. They then meet Anna Fang leaving the wreckage of the Airhaven who takes them into town.
Katherine is found out and has to run away from the engineers guild. She finds out her dad built the MEDUSA before she leaves however. As she is outside she sees a cannon appear out of the roof of the building she was recently it. MEDUSA is aimed at a city looking to attack London. It is blown up instantly by MEDUSA. London people are cheering but Katherine is scared.
Anna Fang takes Tom and Hester into town to discuss them coming with her again. Tom recently found out she was a spy and is hesitant to go with her again. He ends up agreeing.
