A saviour?

Coming around the trunk of a wide three, just a few feet from Lillian, was a young woman, holding a longbow in her hands.
The weapon was aimed at Lillian, but once the naked half-elf had halted, the woman lowered it, looking just as surprised as Lillian.
“Who are you?” The woman asked.
“Lillian! I’m fleeing from something!”
“What!?” The woman asked on, struggling to understand what it was that was happening,
“Big black thing with a massive dick! Got hit by a bolt, so I got away, just fell down a waterfall. It could be following me, so move!”
“Right.”
The woman seemed to coming to terms with the situation now, and grabbed Lillian’s right hand, pulling her with her as she started to trot through the forest.
With the woman leading Lillian on, they could make relatively good speed, and Lillian felt certain that at least the beast would have too make a larger effort catching up with her.

The woman, whose soft green cloak was flapping into Lillian, led her into a gorge that would probably be fairly hard to spot for someone who was moving fast.
However, the dense growth of foliage and plants wasn’t too pleasant to move through, especially not in the nude, and Lillian had to avoid branches that came flapping towards her.

But, once the two had gotten further into the gorge, it widened and the vegetation became sparser, until it finally ended with bowl-like shape. There was a small pond near the rock-walls at the end of the gorge, and when she looked up, Lillian could see that the foliage covered them from being noticed from above.

“So,” the woman began, having let go of Lillian’s hand, “who exactly are you, Lillian?”
“Well, I’m from Tabriz and came here to find the elves.”
“The elves?” The woman said, but then noticed the shape of Lillian’s ear and added:
“I see. And then the natives captured you and decided that you would make a fitting sacrifice?”
“Yes, but how could you guess?”
“Oh, it’s the time of the season. The Ydra’z are going through their mating period, and the natives prefer to sacrifice outsiders, if given the opportunity.”
“Ydra’z? Is that what that beast is called?”
“Yes, it’s Elven. But most people call them Stalkers. The common theory is that they’re the product of some mad magician’s experiments.” The woman rolled her eyes and sighed as she said the last thing.
“Ah, magicians.” Lillian more or less shared the woman’s view on magical experiments.
“Yes, and as they are all male, they rely on human womenfolk to deliver their young ones.”
“So I was supposed to become the mother of a baby-stalker?” Lillian remembered that the beast had ejaculated into her (not something that was easy to forget) and felt worried.
“Yes, but since they have low fertility, I wouldn’t be worried if I were you.”
“Low fertility?”
“Yes, some women have been by their side for weeks without becoming pregnant. I helped to save a young elf that had been a prisoner of the beast for more than three weeks without being fertilized.”
“Who are you? Why do you know this?” Lillian asked, confused and realizing that she didn’t even know the name of her new acquaintance.
“I’m Kathryn, a ranger of these woods.” The woman answered, her voice carrying a certain pride when she mentioned the latter part.

Finally, Lillian took a good look at the woman: she was a brunette with a very attractive face and healthy, tanned skin. Below her long cloak, she was dressed in a tight green leather top that left her midriff bare and a pair of equally tight brown leather pants.

“Well Kathryn, what’s next?” Lillian asked, figuring that the ranger would know best what to do.
