If Vesemir were to be honest, he certainly would not deny that he truly wanted Kaer Morhen restored to its former glory. For an old man who had personally lived through the Witchers' most glorious age, it was what he thought about day and night—and also something impossible to achieve. During that massacre, Kaer Morhen—the largest gathering place of Witchers in the world and once the headquarters of the Witcher Order—had been breached. The apprentices and Witchers had all died. Vesemir alone had survived. He was also the oldest Witcher left in the world today.
It had taken the Witchers barely a hundred years to fall from glory into decline. They had gone from humanity's protectors to mutant bastards everyone wanted dead. Vesemir had no doubt that if all the Monsters in the world vanished one day, the Witchers would be the next to suffer.
Did he want to restore their former glory? Of course he did. He dreamed of it. But he only dared dream about it. There were only four Witchers of the School of the Wolf left, and they knew no Mage who could help conduct the Trial of the Grasses. Not to mention the difficult-to-obtain materials—and the greatest difficulty of all: apprentices.
Even if they could perfectly recreate the Trial of the Grasses and raise its success rate to the highest possible forty percent, only four out of ten apprentices would survive. In this day and age, who would be willing to let their child become a Witcher? No one.
So Kaer Morhen returning to glory had been nothing more than a dream—but today, that dream had come true.
First, the ruined castle had been restored with Reparo. Then the Mage showed Vesemir an entirely different kind of "Trial of the Grasses." Vesemir would have wagered
