Go to the castle

As you move towards the castle you leave your horse in the forrest and move closer.
You expect that this place is heavily guarded and you will have to avoid detection at all costs.

As you see the road to the castle you see multiple soldiers dressed in black and then you realize the amazons have failed.

In a long line the amazons are getting herded towards the castle. It looks like a sad procession. They all have been, deprived from their weapons, stripped naked and have their hands tied behind their backs. Rope is looped around their necks and keeps them **** to walk in a line. It is a sad sight to behold.
They all look deeply ashamed and stare down at the ground in front of them. The soldiers look delighted with their victory and lecherously look at the captured Amazons.

"We are going to have fun tonight boys. The witch said we could keep all of them except their leader." One of the soldiers laughs.

You then notice Ann.
She is completely naked and her arms are bound behind her back in a reverse prayer position. Unlike the other amazons she does not look down and has a defiant look on her face.
She is being frogmarched towards the castle by a young woman dressed in leather. The woman has a pale face and dark hair, dark lipstick and a cruel smile on her face.
You notice a whip hanging from her belt as well as the sword from Ann.

She teasingly gropes Ann's ass and laughs at her.
"Faren looks forward to play with you Ann. You will be the first Amazon general to be her toy. But do not worry these men will take great care of your sisters." The woman chuckles to the defiant looking amazon."

You realize she is most likely the protege of Faren.

As the amazons get marched into the fortress you notice you can climb over the westwall.
You manage to use a grappel to climb the wall without being detected. As it starts to turn dark you consider your options.

Perhaps you could try to save the captured Amazons from those cruel soldiers. If you succeed you have more help to complete your mission.
However you can also leave them and save the princess. Or perhaps you should go straight for the witch and finish her off. She is the main threat after all.
