Check the chieftain's dwelling

You enter the village with stealth, but it's impossible to pass the guards at the door of the chieftain's dwelling. They are not wearing any armor, and they have short spears.

Using the element of surprise, you strike quickly with your sword and slay them both.

There is a long corridor, and the Chieftain is drinking alone, posing his feet on a female human slave who has piercings on her nipples and genitals. She eats food rests from a pet bowl. The goblin laughs and plays with his golden crown and his white beard.

He notices you, but he's not frightened. You can run and try to kill him, or you can defy him.

If you start the combat now, the other goblins may find it unfair and try to kill you even if you win.
If you defy him, you can earn the respect of the tribe, and you can force them to reveal the location of the stone or help you.

What do you do?
