Visit the brothel

Parking your horse you decide that checking out the brothel might be the best move.
It will also give you and idea of how the women here are getting treated.

The inside of the brothel is roaring. Men parade around with women in various states of undress, drinks and food passed around. You walk through the entrance of the brothel, trying to not draw attention. Men of all sorts are being lead away by the women to bedrooms. You scan the room for any threats when you notice a familiar face.

Eretria.

You barely recognize her without her leather clothing and knives but it clearly is her.

Eretria is a legendary rogue and mercenary. And she is every bit as skilled as she is deceitfull.
A few years ago you had worked together with her in stealing a gold treasure from the trolls. After obtaining the treasure she had seduced you and the two of you had a long passionate night together. However the next morning you had found yourself with your wrists tied to the bedframe and Eretria and the treasure gone.

The attractive and short brunette was in a skimpy bra and thong that perfectly showed off her slender and attractive body, laughing and carousing with one of the witch's soldiers.

You know that unless she has considered a career switch she is not a howr and is most likely here undercover to gather information much like you planned to.[

You know that she is highly skilled in deceiving, seduction, pickpocketing, poisons, acrobatics and ****.

You watch the two, Eretria playing the innocent maiden as the soldier regals her with stories of his heroism no doubt. After a bit, Eretria stands up and takes the man by the hand, leading him up a set of stairs.

It is clear that she is not aware of your presence. Perhaps it is best to leave her alone and focus on gathering information and go after the witch. However you could also follow her and get back at her for stealing the treasure from you. She is not expecting you and you could probably take her if you catch her by suprise. However a third option comes to mind.... you could perhaps see if the two of you could join forces. Her skills for stealth and entering and escaping places without noticed are legendary. If the two of you would join forces you could use her skills in your fight against the witch.

What will you do?
