Why not?

Geralt sat on the edge of the bed, taking small sips from the mug that Vesemir provided him with. He could feel the effects of the brew working its magic, "I should really ask Vesemir what he puts in this." He said aloud. "On the other hand, I most likely don't want to know." He mused. Geralt finished the contnets of the mug and set it down on the table where they drank last night, which was covered in other mugs and bottles. Geralt still felt a little woozy from the ****, but was feeling much better, as he made his way slowly to the forest to meet up with Vesemir.

"Did it work as well as last time?" Vesemir asked as soon as Geralt appeared into view.

"Just like a charm. I don't want to know what you put in it though." Geralt said cautiously.

"You're right, you don't." Vesemir said as he started into the forest. "Today, we'll deal with some Nekkers that have made a nest here, then you can go. That should things slightly safer out on the road."

"Nekkers? So do you know where the nest is?" Geralt asked. Nekkers continue to spawn unless the nest is destroyed unfortunately, so Geralt learned the hard way.

"The nest is just over there." Vesmir pointed out into the forest.

"I don't see any Nekkers."

"Me neither, you have some grapeshot?" Vesemir asked. Grapeshot is a bomb used to destroy Nekker nests.

"Of course." Geralt said as they moved up cautiously towards the nest. Suddenly a Nekker jumped out at him from the woods. "Nekkers! They're in the woods, watch out!" Geralt warned Vesemir as he unsheathed his Silver sword and took a defensive stance against the charging Nekker. Geralt could hear the other coming from deeper in the forest "Master, back to back!" He shouted to Vesemir who was eyeing the woods warily with hi yellow eyes.

"Good idea kid. What's the plan, Aard then grapeshot?" He asked

"A little busy here." Geralt said as he fought the Nekker.

"Oh sorry, would you like some help?" Vesemir jokes sarcastically. Geralt blocked the taloned claw strikes of the Nekker and heard the sound of the others coming closer. Geralt didn't have any more time to be on the defensive, so he used Igni to shoot flame out of his hand, and lit the creature on fire. The Nekker leaped back and wailed in pain as he was burning, Geralt ran up to him and ran him through with his sword before pulling it out and lopping the creatures head off. The flame from the burning carcass started to spread across the leaves on the forest floor. "That could be a problem Geralt." The wise old Witcher noted.

"It could be an advantage." Geralt said as he watched the Nekkers come up to the burning leaves, but not cross it, it seemed as if they were scared of fire. "You don't have any sentimental emotion for this forest do you?" Geralt asked looking at his master, making Vesemir sigh.

"Always making rash decisions, just like Ciri. Try not to burn too much down, it adds to the image of Kaer Morhen being haunted. It makes sure that I don't have to ward off a curious group of peasants every other day."

"I'll try to keep that in mind." Geralt chuckled as he turned to face the growing flame, and the Nekkers trying to get around it.
