Steal and you run away

With anger and your body reaching your limits, you use your knowledge to steal an extremely valuable gem.
At night, you use the lonely corridors of the mansion, and you quickly leave the place unnoticed.

When they discover your crime is too late, you are far away from the city, and the noble lord has other important issues to attend. Now you are a wanted person, and you may attract some low-tier bounty hunters or novice adventurers.

You continue your journey alone, on foot, but you have something that can be exchanged for a high-level spell and you can finally return to your world.
You just have to find a powerful wizard.

The guard can't chase you through the woods, but the place is dangerous, you are dressed like a maid, and you have only a broom as a weapon.
Hidden in the vegetation you find a small house, a gnome is smoking a pipe and singing playfully “A pipe is the fountain of contemplation, the source of pleasure, the companion of the wise and this is a good eternal vacation"

You hold your laugh, the funny gnome is so weird.

You can ask the gnome for direction and maybe for help, these little creatures are well known because of their magical powers, but they are unpredictable!
Or you can continue through the forest and try to find a road, far away from the city, however the woods are always a risk.
