A Mighty Fortress (novel)

Both conspiracies enjoin "Temple Loyalists", who view the Church of Charis as an abomination that must be destroyed, with secular leaders, who want to take back their nation from the foreign occupation and both seem to be getting very well organized.

While Merlin uses his advanced technology to maintain a constant watch over these groups, he, Emperor Cayleb and Empress Sharleyan (who is now pregnant with her first child) decide not to move against them now and wait until they can crush all opposition in a single stroke.

Nonetheless, Thirsk turns out to be a shrewd operator, as he manages to get his crews trained very well while changing the general practices of the Dohlaran Fleet, which earns him even more enemies in Dohlar and in the Temple.

In Tellesberg, Archbishop Staynair is preparing for his journey to Corisande and reluctantly tells Baron Wave Thunder about the trunkloads of reports Adorai Dynnys handed to him about corruption within the temple.

Merlin, who is notified about the abduction by OWL too late to save Hahskans, moves against the conspiracy in Manchyr, sending an anonymous message to Sir Koryn Gahrvai, the son of Earl of Anvil Rock, who proceeds to arrest the conspirators, among whom they find the former Intendent.

Merlin takes the opportunity of Sharleyan and Cayleb's stay in the palace during winter to go on another mission to Zion, where he disguises himself as a Silkiahan merchant by the name of Ahbraim Zhevons and makes contact with Madam Ahnzhelyk, The Circle's most prominent ally.

Rather, he will fund all the charitable orders so as to present a more gentle face for mother church to help those who will be hurt in the Holy War that has just been declared and Trynair agrees to support Duchairn's decision.

Merlin, in turn, notifies the regency council about the Northern Conspiracy and how the Emperor and Empress have known about for some time, waiting for them to organize so as to decapitate the resistance in one fell swoop and snare the treasonous Grand Duke of Zebediah along with them.

In Charis, Master Howsmyn and his researchers begin developing an exploding shell for the navy's new iron cannons, while Earl Grey Harbor opens clandestine negotiations with King Gorjah of Tarot.

Caught with their most of their fleet badly out of position and unable to do anything about the Church's move on Tarot, Cayleb and Sharleyan decide to send Earl Lock Island and his 25 ships against over 120 galleons, though only 90 are armed.

Lock Island then leads a daring nighttime ambush against the Church's fleet and manages to catch it completely surprised, eliminating an entire column of ships before they can respond.
