Last Exile - Season 1 Episode 24 Sealed Move

A portion of the Guild fortress breaks apart and falls away from the Grand Stream into Anatoray. Claus escapes in the vanship that was brought with them to the Guild stronghold and takes Alvis and Dio to Norkia. Dio is then left in the care of the Mad-thane residence, which has been converted into a makeshift hospital. Claus takes Alvis back to his wrecked house, where they stay overnight. The combined Anatoray and Disith alliance fleet launches a surprise attack on the Guild fleet and, helped by the vanship squadrons, emerges victorious. It continues to pursue the withdrawing Guild ships into the Grand Stream. When Claus and Alvis are finally able to contact Lavie and the Silvana with Lucciola's communicator, they are told to make a rendezvous at the Dragon's Fangs.
