The Leper King

The morning sun filtered through the narrow windows of Baldwin's chambers, casting golden streaks across the stone floor. Ethan sat at a wooden table, his bandaged hands steadier than they'd been in days. The garlic-turmeric paste and honey salves, applied diligently by Brother Gerard, had begun to show results. The lesions on his arms were less inflamed, the raw edges of his sores slightly less angry. The willow bark tea dulled the constant ache in his joints, giving him a clarity he hadn't felt since waking in this body. It wasn't a cure—Ethan knew leprosy required multidrug therapy far beyond this era's reach—but it was progress. For the first time, he dared to hope he could slow the disease's march.

Brother Gerard entered, carrying a small vial of amber liquid and a bundle of dried leaves. "Sire, I have acquired frankincense oil and neem leaves, as you requested," he said, setting them down. "The merchants in Acre drove a hard bargain, but they swear by the neem's purifying qualities."

Ethan nodded, his mind already racing. Neem was promising—its antibacterial and antifungal properties could complement the turmeric and garlic. The frankincense oil might reduce inflammation further. "Crush the neem leaves into a paste with the turmeric mixture," he instructed. "Mix a few drops of frankincense oil into it. Apply it twice daily, and keep a record of any changes."

Gerard's brow furrowed, but he no longer questioned the king's orders. "As you command, my lord. The court speaks of your vigor today. Your presence yesterday inspired many."

Ethan allowed a small smile, hidden by his silver mask. His appearance before the court had quieted some of the whispers, though he knew Sibylla and Raymond were still maneuvering. Baldwin's memories, now fully integrated, gave him an edge—he could anticipate their moves, read their intentions. But military strategy alone wouldn't secure the kingdom. Saladin's army was closing in, and Jerusalem's resources were stretched thin. Ethan needed more than knights and prayers. He needed innovation.

As Gerard applied the new paste, Ethan's thoughts drifted to his old life. He wasn't an engineer or a scientist, just a barista with a knack for trivia and a few history podcasts under his belt. But he knew enough about the modern world to recognize the gaps in this one. The 12th century lacked so much—sanitation, efficient agriculture, basic mechanics. Could he bridge that gap? Introduce technologies that were simple yet transformative, without arousing suspicion?

He started small, picturing the kingdom's needs. Jerusalem relied on trade and agriculture, but its fields were parched, and its sieges were brutal. Irrigation could boost crop yields—simple ditches or aqueducts, like those the Romans had built, were within reach. He'd read about medieval waterwheels; could he refine them for grinding grain or even powering basic tools? And for war, the Crusaders' armor and weapons were effective but heavy. Could he introduce lighter crossbow designs or better siege equipment, like counterweight trebuchets? These were centuries away historically, but with Baldwin's authority, he could nudge the kingdom toward them.

"Gerard," Ethan said, testing the waters, "how do our farmers water their fields?"

The physician blinked, caught off guard. "With buckets from wells or rivers, sire. In dry seasons, they pray for rain."

Ethan nodded, his mind sketching a plan. "Summon the master of the royal works. I want to discuss... channels to bring water to the fields. Like the Romans did."

Gerard's eyes widened, but he bowed. "I will fetch him, my lord."

As Gerard left, a squire announced the arrival of Balian of Ibelin. Ethan straightened, grateful for a familiar ally. Balian entered, his surcoat dusty from the road, his expression grim but resolute. "Sire, the scouts have returned from Montgisard. Saladin's army is encamped near the valley, overconfident in their numbers. The terrain favors us, as you predicted."
