Discovered attack.As the systems return to normal, Alvis awakens with no recollection of what occurred during her trance. Returning from his meeting with Vincent, Alexander orders the Silvana to intercept the Urbanus at a region of jagged rocky spires called the Dragon's Fangs. For the upcoming battle, Tatiana appoints Claus as her navigator. As the Silvana enters the Dragon's Fangs guided by its combat vanships, the pursuing Urbanus and two sister ships, the Martinus and the Julianus, seal the escape route behind them. As two more sister ships, the Georgius and the Sebastianus, are spotted further into the Dragon's Fangs, Alexander orders the Silvana to quickly ascend after momentarily being pinned by the Sebastianus. Vincent orders the Georgius to ram the Silvana, but it accidentally rams the Sebastianus instead, destroying each other. Then, Vincent orders the Martinus and the Julianus to anchor tethers to the Silvana, preparing the Urbanus to ram the Silvana. However, Alexander orders the Silvana to fire on the surrounding rocky spires, causing them to collapse and pull down the Martinus and the Julianus. The Urbanus is forced to withdraw, but the Silvana cannot detach its tethers. Tatiana and Claus watch as the Silvana sinks below the clouds.
