Take the sword and run

You take the sword, but a wall collapses and hits one of your legs, wounded, you try to escape, but you need tome to recover, you can barely walk.
The sword speaks directly to your mind and says "You save me from these ugly goblins, now, I must repay my debt"

The sword casts a shadow around you, and the goblins are disoriented, they can't see you!
You move, making a great effort to walk, and you finally escape from the village. When you feel safe, you take some time to recover.
The sword speaks again and says "I must rest too if you need me, say my name, goodbye traveler from another world!" and after that you only listen to a snoring sound.

One hour later, you can walk again and continue your journey, however, the goblins are tracking you, and their hunters are everywhere!
You must leave this place as fast as you can!
