Here is the full list of all 25 Niflhel's Fables: The Book of Gypsies achievements.
This is how legends are born
Swordsman
Not long but bright
Where is the horse?
I don't talk to strangers
Very scarry stories
Beautiful melody
Steam, steam, the all unseen
Maybe it was necessary?
Village with a bad reputation
It's interesting what's in there!
The right remedy
Why did you leave your horse
Don't talk to strangers horses
A deal's a deal.
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.
Thunder and lightning
Endless melancholy
Get your reward
Where is your head?
From dawn to dusk.
