Wow toady, you totally cleared up every doubt I ever had. Also, Bill Nye is a douchebag.
But being totally serious, having burrows will make my meta-project of a family/caste oriented Dwarven underground city possible.
Lowest castes would live in the outermost parts of the city; exposed to both goblins and megabeasts. Farming, brewing and feeding the masses, they are often killed in sieges, as the defenses are somewhat weak beyond the grand wall. Then comes the warrior caste, who train day and night; their mighty armories and arenas stand testament to the dwarven might. They are seperated by a wall from the lowest caste, with marksdwarves standing upon a gatehouse to to the entrance. Then, Next comes middle class of crafters smiths, and tradesdwarves. The smiths are the closest to the warrior caste, as they supply them with their equipment. Next come the craftsdwarves, mostly made up of women, they toil and labor to supply the nobles' every whim.
Speaking of nobles, that's the next caste(With the notable exception of the broker, who lives with the craft caste, the dungeonmaster, who lives with the warriors; training the mightiest of beasts for the arena and the clerk, who is the only dwarf who travels freely from caste to caste, gathering info and basically making sure it doesn't go to shit. He has his office in the nobles' quarters.) The noble quarters feature only the finest of each caste, along with all the nobles. They are the top 10%, for a reason. Yes, there are almost no deaths or tragedies in this place, and it is coveted by all. These nobles are guarded by the fiercest of warriors, who are sent into the arena to prove their valor. It is considered an honor to be amongst the noble caste, as the royal guards are treated as such.
Hell, I could do enough writefaggotry on this idea that I could just write until the update came out. Good on you, toady!
Highlights and locations:
Untouchables -
The great fields, which even though is in the mountain, is said to glow like day from all the plants
The Legendary feast hall, which is the only real luxury the poor chaps have
The great wall, which is really the smoothed wall of the mountain.
The pit of petulance, which is where pretty much all the trash in my fort ends up
Warriors -
The sparing halls, which have gutters for all the blood that is spilled
The grand arena, which is the one place the nobles are not allowed to go, other than the dungeonmaster
The armory, which is filled to the brim with every weapon and armor in the world.
The proving grounds, which is a section of the arena where all new warrior migrants have to go to prove themselves. I do this immediately so if they die(which is more than 50% of the time), no one gets a bad thought.
Crafters -
The great drinking hall, which is said to have every ale available in the world
Thors' Forge, fueled by magma, is where all weapons of the fort are made
The halls of gold, decorated by every craftsdwarf in the bloody caste, is truely the object of plunder for the goblins, as it consists of every wealth among multiple floors. It is also where coins are stored.
Nobles -
The Royal Barracks, which consist of the forts' mightiest warriors
The champions' hall, which has plundered loot and war trophies from every civilization. It is here that the champion resides.
The nobles' quarters, self explanatory
The Kings' castle. Wow. Engraved, adamantine throne, bauxite moat with lava. The champions' hall is located inside.
