Typical dwarvish. Very hierarchical. An industrious proud people, full of skilled craftsmen who pull their weight for the greater good of society. Due to seasonal attacks from a goblin horde nearby, they've built fortification that protect them, and during attacks the wall guards are helped by alchemists fire. Unfortunately that last step failed during the most recent attack, which was also unusual in its strength and strategy (the horde got outside help), causing the fortress to fall. While looting, the invaders opened the floodgates that had redirected the river, thus drowning any survivors except one.
