"Haven: Chapter Seven of The Good Prince" is the sixty-seventh issue in Fables.
Publisher's summary
The Emperor and his minions can't stand the fact that the new kingdom of Haven exists in the very heart of his empire, a treasonous signal to anyone that his power isn't as absolute as he claims. So he sends his vast and deadly armies against it, to wipe all trace of it from the face of the earth, as "The Good Prince" continues.
Plot
The armies are face to face. After ordering his death, Trusty John comes back to life again to show the Empire that the residents of Haven cannot truly be killed. In Flycatcher's kingdom, only his magic can work. Flycatcher makes a deal with the general, whoever wins a one-on-one fight wins the day. Rather than fighting the general, Flycatcher is forced to fight a giant troll called Grinder - but instead of killing the troll, Flycatcher spares him and welcomes him to his kingdom. The Empire's army attacks them anyway, however Flycatcher has one more trick up his sleeve: he turns everyone into ghosts to help in the upcoming battle.
