You have no magic to enhance your abilities, so you must rely on your charisma and knowledge to persuade the guards and servants to make an exception, allowing you to speak with the nobles and seduce a noble lady.

You spot a blonde girl in the gardens wearing a beautiful white dress. However, the guards are strict and refuse to let you pass.

But you have a nice guy aura. The lady approaches and makes a sign with her hand, and the guard immediately lets you pass so you can speak with her.
"I never noticed you in town, you must be new on these lands" she smiles.

You explain that you come from a land far, far away, and tell her stories of towers that reach the skies and carriages that move without horses.

After a long conversation, she finds you fascinating and invites you inside for some tea.

You share a cup of tea with her, and while sitting in the hall, you spot the noble lord. He notices you and smiles.

The noble lord is a big man, he's tall and muscled. The man is wearing silk clothes, and his fingers are full of rings, and he has a collar with a big golden key with the word "D6".
The stone!! This key will lead you to the stone!

You must decide what to do next.
You can try to seduce the noble lady and carefully ask her about the noble lord, or you can attempt to speak with the lord directly.
