Follow her

You wait for a moment and then follow. At the top of the stair well is a long corridor. Closed doors line the walls, no doubt the whores entertaining their clients. You hear laughter coming from down the hall and follow the sound.

You stop by a corner room, the sounds of conversation coming from the other side of the door.

"So, are you a warrior?" You recognize the voice of Eretria.

"A warrior for Faren the Witch! One of the best!" Answers the drunken male.

"So, what great missions are you performing for the witch now?" Eretria asks with perfectly played admiration in her voice.

"Now my dear, I can't tell you that. Pretty things like you shouldn't worry about that?'

"Aw, but what can I say to people when I say that I met a big, strong, important warrior?"

" All I can say is that we're investigating the rumor that a group of Amazons is trying to attack the witch as we raided several of their villages. We are planning to capture that group and then raid even more of their villages to turn them into slaves..... but the rest doesn't concern a maiden like you."

"That is.... so cool. Here have another glass of wine. We will toast on that" Eretria says.

You hear them toast and then the soldier drinking his wine.
"Wait... I feel.... weird... what... is..." The soldier lets out and then you hear his body crash on the floor.

"Must be the sedatic. Sleep, brave warrior and thank you for the information." Eretria giggles.

You consider your options. You could burst into the room and attack her but perhaps it is better if you talk to her and see if the two of you can become allies.
"What will you do?"
