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