Think about it; the first books write about the Fourth Succession War, which start because his parents (rulers of two out of five Successor States, for the uninitiated) get married. The last CBT fiction novels were about the Civil War in which he deposed his Usurper sister Kathrynne, renounced his claims as a Successor Lord, and became the Precentor-Martial of Comstar again, effectively making him the leader of the New SLDF, head of the largest army in the Universe, and personally charged with keeping the peace and staving off the Clans aggression.
For further evidence, let’s look at all the trilogies:
Warrior trilogy, by Michael A. Stackpole: Story of the 4th Succession War
Blood of Kerensky trilogy, by Stackpole: Story of the Clan Invasion, including the leaders of the Succesor States responses to it.
Legend of the Jade Phoenix trilogy, by Robert Thurston: specifically the life of a member of the Jade Falcon Clan. Not related to Victor.
Twilight of the Clans, actually an 8-book set by several of the big authors: The story of the formation of the new Star League (at the behest of Kathrynne Steiner-Davion, the sister who had their mother assasinated), the unified campaign against Clan Smoke Jaguar (led by Anastisius Focht, Victor’s great-uncle, and Victor), the jounrey to the Clan homeworlds to eradicate the Smoke Jaguars (where Victor ultimately saves the day), the futures of Thurston Jade Falcon characters, Victor’s Trial of Refusal against the Clans to stop the Invasion, and Victor’s return home to find Kathrynne has now completed her usurpation of the throne their parents left him. Oh, and the acceptance by Theodore Kurita (ruler of the long-time enemy of Victor’s realm, the Fed-Com) of Victor’s relationship with Omiko, Theodore’s daughter.
“End Game trilogy” (series of three books directly related to one another, but never listed as a trilogy), by Loren L. Coleman: The story of the Fed-Com civil war in which Victor finally deposes his sister, Omi gets assasinated (at Kathrynne’s demand) but not before giving birth to Kitsune Kurita (Kitsune are many-tailed fox demons known for trickery in Japanese myth, Victor’s dad Hanse was known as “The Fox” for his military cunning), who is secreted away and raised as a child of one of Omi’s cousins. Victor formally dissolves the Fed Com into it’s two former states, the Lyran Commonwealth (now the Lyran Alliance), and the Federated Suns, and leaves their care to his two remaining siblings (Arthur is “killed off” in the beginning of the series), Peter and Yvonne. The Inner Sphere is left in an uneasy peace, and the Clans are too busy fighting eachother to be of any imminent threat. This series was meant to wrap up Battletech’s fiction, back when FASA was going out of business, and before series-creator Jordan Weisman’s new company Wizkids Games bought up the rights and authorized Fanpro to continue the Classic series (Weisman was more interested in jumping ahead ~80 years to start a new product line). Interesting note, Stackpole wrote the original outline for the first book Patriots and Tyrants.
So, any questions?
