his family survived Steiner's siege of the Dresari palace: his sister Joanna. After a short reunion, Ian and Joanna are separated again as the Resistance mobilizes to assault Steiner's stronghold. They make a brief detour to save the coastal town of Vale after Steiner threatens to bomb the town due to allegations of links to the Resistance. Not only does the Resistance save the population, but Ian defeats his uncle's murderer, Duncan Burke, in a heated duel. Pushing into the cities, the fighting heats up and Resistance casualties mount. Joanna informs Ian of an old armory cache hidden somewhere in the city, invaluable for assaulting the Dresari palace, now the headquarters for the Steiner occupation. Right before the Resistance prepares to locate the armory, Joanna and her Lance are ambushed by Steiner forces, leaving her wounded and in mortal danger. Ian makes a choice, between rescuing his sister from certain death or securing the weapons cache. Whatever the player chooses, Ian and the Resistance fight one last battle against House Steiner at the palace, putting an end to the war. However, the fight is not yet over for Ian, as William shows up in a modified Daishi, challenging Ian to a duel. Ian defeats William and finally frees the planet from Steiner's grasp. Depending on the player's choice before the penultimate mission, either Joanna or Ian will ascend the throne as Duchess/Duke. Black Knight Mechwarrior's expansion, Black Knight, takes place several years after Vengeance, and gets its name from the organization of mercenaries the plot revolves around. The Black Knight Legion fall under the employ of the Lyran Alliance, who wish to reclaim Kentares IV from Ian Dresari. Ian chose to find the weapons cache, leading to his sister's death, resulting in many of his allies abandoning him. House Steiner, unwilling to pay the Legion mercenaries for their fulfilled contracts, decides it would be much cheaper to betray the Legion, and nearly wipes it out in a surprise attack. Legion remnants seek justice against Maj. Clarissa Dupree, mastermind of the Lyran attack against the legion, while also continuing with their mission to overthrow Dresari. They eventually find and kill Ian on Kentares, then travel to Voltrat III to find Steiner liaison Clarissa Dupree. Eric McClair, CO of the Legion, defeats Maj. Dupree in single combat, destroying her Mad Cat MkII, then proceeds to shooting her ejection pod, killing her instantly.
