Unicorn

Xianxia v8.0

Encounter in the Forest. (I encountered her at Level 10, my character had only one encounter with a Minotaur after losing to that minotaur) Possibly a Unicorn?

As you wander the woods, you stumble upon a large clearing. The place is pure - so pure that the rest of Mareth looks like a corrupted wasteland in comparison, which given the current state of things, isn’t that far from the truth. In the center of this natural masterpiece sits a large stone altar, upon which rests a magnificent white shield ornamented with gold filigree. As you approach the shield, a powerful wall of force stops you a few feet away from the item.

“None shall take this sacred relic from this place without my consent!”

You turn over just in time to see a massive horse-like figure charging at you, barely managing to move out of the way in time to avoid being trampled. Your assailant is now standing between you and the altar, letting you get a good view at the grove’s ostensible guardian:

The woman has silvery white hair flowing around her perfect visage; and her sizable E cup would make most women back in Ingnam green with envy, then again, most things even somewhat female here in Mareth would cause the same reaction. The comparison to a human, however, ends there. Below her waist is the large lower-body of an immaculate white horse. Her ears are covered with silvery white fur and while at first you mistook her for just a centaur warrior, the spear-like spiraling horns on her forehead warns you that there might be more to her.

“Just leave and I won’t have to attack you. I swear on my honor that I won’t give chase should you leave peacefully. This is for your own good.” You ask her why she is defending this relic and what it would take for you to gain access to it. She eyes you as if trying to figure out your intentions then sigh.

“Only the pure of heart and body may be allowed to pick up this shield, Marae herself tasked me with guarding it. If you truly wish to prove your worthiness then I will ask of you that you perform a task for me.”

What task?

“In the darkest reaches of the forest lurks a terrifying creature of great corruption known as a nightmare. It is anathema to purity and must be disposed of. Slay the nightmare and I will grant you access to the shield.”

On those word you leave, better seek out this creature as fast as possible.

Not sure if "Darkest Reaches of the Forest" means the Regular Forest or the Deepwoods
