- "Never burn a bridge unless your foe is on it, Captain."
Lord Selnikov first appears as a co-conspirator of Princess Anevka Sturmvoraus. He is a member of the Knights of Jove, re-purposed to supporting the return and success of their Mistress aka the Other aka Lucrezia Mongfish. Anevka orders him to ensure the deaths of all the theater attendees who imprinted upon Agatha's voice when she was performing on stage in the palace theatre.
Lord Selnikov later reappears using the title "General Rudolf Selnikov, Commander of the Knights of Jove". (Note that while it had been plausible that Lord Selnikov and General Selnikov were two separate people, it has since been established that they are one and the same.) His Lordship leads the war-stomper invasion of Mechanicsburg on behalf of House Valois. This is part of the Knights' attempt to restore the Storm King's line to the rulership of Europa using manipulation of legend, circumstance and timing to their best advantage. Unfortunately for the General, he is summarily by a very determined Gilgamesh Wulfenbach in a massive, artificially-generated lightning strike.
Though officially dead, Selnikov's head was retrieved by Captain Vole under instructions by Gil to deliver to Dr. Sun for revival and memory retrieval. He was given a leonine offer of alliance with the Wulfenbach Empire to protect him from any reprisals from the Knights of Jove, whom Selnikov compared the Wulfenbach administration favorably against in terms of safety against deadly intrigue.
He was later consulted by Boris over the existence of the Spark infecting wasp that may have been used on the Baron.
Married, but unhappily. Apparently he was very unfaithful, Agatha H and the Clockwork Princess page 343 , mentioned his wife was shopping in Paris while Rudolf has a implicit affair. Given his being revived after death he is considered dead in the eyes of the fifty families, and as such his wife can claim full legal right as his widow while his revert to his insufferable nephew. His widow is later revealed to be Margarella Selnikov, fleeing from assassins in the employ of the Knights of Jove and enacting her own agenda against Martellus von Blitzengaard.
The Works Edit
Lord Selnikov also appears on one of the cards in The Works as a living "head in a jar". And now thanks to Doctor Sun he looks just like himself. Lord Selnikov's card details are Villain and Spark. While the former is fairly obvious, no evidence of the Spark has been displayed as yet in the canon (unless the War Stompers he led were his creations, but again, this has not been said or shown).
The Works also contains a card for Lady Selnikov.
