rsonally responsible for rescuing two of Hawat's loved ones from Harkonnen oppression Although documentation of the details of this feat is lacking, the Duke's daring and courage must have endeared him to his Mentat It is, thus, not surprising that before Hawat had been with Duke Mintor many years he almost literally gave his life for his Duke In a skirmish with offworld raiders at one of the Duke's ranches, Hawat dodging to escape a sword slash in the groin, took it instead m his left leg He bore the scar, and the occasional pain, with pnde Hawal's regard for his Duke, a bullfighting addict, led him to develop an extensive bull-breeding program Using his abilities to analyze genetic qualities Hawat set up breeding farms and outlined feeding and nutritional experiments He also designed d new arena for the Duke, supervised its construction, and took charge of the colorful pageantry known as the Atreides Tourney Since Hawat never missed a corrida in which the Old Duke took part, he was present the day a great bull caught the Duke on his horns After the Old Duke s death, Hawat trans ferred his allegiance to Duke Leto who turned his attention from his well-run estates to concentrate on espionage defense at\l the expansion of his sea and air power Hawat served his Duke brilliantly m every interest military, political economic, social and personal In tact it was Hawat who investigated the Bene Gessent school and Jessica before reluctantly having her escorted to Caladan to be Duke Leto's concubine He became even more useful after Paul was bom Suspecting that his son might have mental capabilities, Leto gave Hawat the responsibility of setting up Paul's intensive 301 training program During these inornate years of Paul's infancy and childhood, Hawat came to love the boy as his own son This love endured to-and manifested itself magnificently on-his dying day The best way perhaps to appreciate Hawat's value to House Atreides is to review his contributions during the move from Caladan to Arrakis a fief that had been held by ancient enemies of the Atreides the Harkon-nens The logistics involved in moving personnel and materiel from one planet to another were appalling, but Leto was confident the task was not beyond his Mental In record time, his confidence was confirmed An even more difficult job was securing the settling of the new capital at Arrakeen especially when all of Hawat's calculations warned him of the high probability of Leto's losing Arrakis to the disgruntled Harkonnens In preparation, Hawat made himself an au thonty on Arrakis, he gathered and digested every scrap of knowledge available on geography, topography, climate, weather and history, as well as on the Bremen and their culture After me move he sent out Grained teams of observers to augment his information Two immediate concerns were communications and military strategy Hawat set up the Duke's own conununicafcons network and enlarged the codes, especially the Atreides hand signs and battle language his creations He deployed the troops, efficiently dividing the guards between the Governor's Mansion and the landing field For future use, he assembled dossiers on suspected Harkonnen sympathizers The most sensitive area was security Hawat spent sleepless days and nights checking every room and all the furnishings of the Residency He set op shields, placed safety devices, cleared me servants, and personally installed the poison snoopers Hawat had made security the core of his instruction to the young Leto, and later the young Paul "The cost of survival is eternal vigilance ' However, despite all his care, a hunter-seeker placed by a traitor after Hawat had inspected Paul's room threatened Paul's Me shortly after the move into the Residency When, in an agony of remorse, he tried to resign, Hawat was reminded that Paul had survived largely through Hawat s own training Leto felt he was more to be commended for Paul's readiness than blamed for his ignorance of an "internal" traitor, whose presence no one-from Duke Leto and the Lady Jessica down to the lowliest trooper-up to this moment had suspected Leto's faith in his Mentat.
