So I read some demographic on these boards recently that said the majority of dwarves in Allanak (also maybe Tuluk too?) were slaves.
This immediately made no sense to me, at least based on the documentation that I read. Why? Because dwarves, with their narrow-minded foci, seem like they would be the absolute worst slaves imaginable unless you happened to find one whose focus centered upon doing what you wanted them to do. Then of course they'd be the perfect slaves! But with all the possible objects of dwarven attention in the world, how rare would this really be? Out of every fifty I would guess you might find a dwarf with a useful focus. Like, if you wanted a sculptor and this dwarf was focused on creating the perfect sculpture.
But even then, what if this dwarf really wanted to make the perfect sculpture of... an elf juggling baby mekillots? All of her sculptures would somehow, some way probably have an elven or baby-mekillot slant because at the very least they'd be subtly taking the opportunity to practice. She'd be sneaking away in the night to stare at mekillots or elves and capture their every movement, curve and feature. Anything not related to elves and mekillots would probably come off subpar except in small, elf-or-baby-mekillot-related details.
This is just one example. Dwarves might make fine labor slaves, with their muscle and short stature, but how many of them are really going to have manual-labor-related foci? Very, very, very few. Most would RELENTLESSLY scheme to escape or find some way to achieve their own ends. Dwarves would be terrible slaves and I disagree with that demographic number in particular, because no one in their right mind would want any but the most select and rare dwarven slave. Even then, I would bet that it would often go terribly wrong.
