Mist is meant to make Dwarves happy, Habuki. You're a monster.
As for me, it's my dwarves that are the monsters although sometimes I am the invisible catalyst that accidentally turns them into the Tolkien flavoured Batman villains they sometimes become.
I decided one time that my fortress had way too many puppies and dogs in it because I don't have a magma vent and so metalcrafting fuel is too valuable to me to waste my charcoal and coke on making cages to stop dogs from fucking when I should be making metal barrels, armour, weapons and tools. So, after training a lot of them to be war dogs in my new kennel, I decided to set the majority of the remainder to be slaughtered, many of them puppies that the children play with because you can't train puppies and you can always use more meat and bones to make practice bolts for your marksdwarves to train with. None of them were claimed as pets yet so no one got depressed or pissed or anything but then, one of my children dwarves fell into a secretive mood.
This alarmed be because I didn't think children could get strange moods since they can't do work or have any labours enabled. But little Strolaf ran off and commandeered the craftsdwarf's workshop and drew some pictures of animal bones. Within a month he had created VOLKANOV the legendary dog-bone coffin...
I never bought all the hoopla about how the highly randomized but very complex and patterned inner workings of Dwarf Fortress often created very interesting stories despite the game's almost complete lack of scripting but now I'm a believer.
