This is how legends are born
Swordsman
It's interesting what's in there!
Where is your head?
Village with a bad reputation
The right remedy
Why did you leave your horse
Very scarry stories
Beautiful melody
Maybe it was necessary?
A deal's a deal.
Not long but bright
Where is the horse?
I don't talk to strangers
Steam, steam, the all unseen
Don't talk to strangers horses
Thanks for being alive
Hold on tight!
A new story begins
Get out yourself, since you're so smart
Especially at night in the cemetery.
Endless melancholy
Get your reward
Thunder and lightning
From dawn to dusk.
