Fics like Titans in the Void

This crossover was inspired by an image of the Executor and the Honour of Macragge in combat accompanied by the question, "Who would win, Vader or Guilliman?" When an ancient relic draws the Executor and the Macragge’s Honour into the same sector, two titanic warships collide over Carthaea Secundus. Lord Vader approaches the encounter with overwhelming force, dark-side intimidation, and the expectation of fear. But Roboute Guilliman doesn't see an unstoppable dark lord. He sees an anomalous warship whose pristine hull suggests a captain accustomed to immediate compliance. Darth Vader expects horror and surrender. The Avenging Son brings disciplined, well trained engagement protocols and combined arms strategy. What begins as a clash of fleet doctrines quickly escalates into the ultimate confrontation, as two legendary commanders battle for supremacy.
