Lie and steal

You start to work for him, and you quickly earn his trust with your polite words, advanced knowledge, and cunning.

After some time, you have the keys to one of his chests, and one night, you take all the money and you escape.
You now have a fast horse, a magic sword, and TONS of money.
With this gold, you can pay for a powerful wizard, and return to your world!

They didn't notice your betrayal until the next day and you escape with total impunity.

You follow the road, and you are ambushed by a big green orc.
He's tall and big, but he doesn't have any armor, and his weapon is just a big stick.

You can fight him or disengage and run through the forest outside the road.
