Dwarf genesis
In the beginning there were the giants in a land befittingly called the kingdom of giants. all manner of giant animals lived and thrived and all sought to the protection of and to protect the giantheart an ancient elemental forest throbbing with the very pulse of creation, things were wild and savage in this primordial world but the giants ruled and protected it.
Storm Giants with domains over thunder and lightning lived in the thunderous peeks.
The calm cloud Giants with domain over Rain and air lived upon the very winds upon their cloudhomes.
Hill Giants with domains over the barren hills and animals lived in their Hilly homes running wild and savage
Fire giants with domains over flames and lava sang and clashed in their volcanoes
Frost Giants with domains over the ridged cold and ice ruled a kingdom in their glacial home.
Mountain giants with domain over earthquakes and the unforgiving mountains thrived in their cruel mountainous castles
and the stone giants with their domains of caves and earth lived in the such places.
One day though the Stone giants in their cavernous homes came across the shiny metals in the rock. golds and silvers and platnums and showed brothers what they had found. all but the Mountain giants who were more concerned with their cruelties were in awe of the lovely things. Still further the stone dwarves dug and found Onyx and diamonds and emeralds. and These too were coveted and beheld by the other giants.
Frost Giants pulled pearls from the ocean.
Fire giants called forth rubies from their volcanic homes.
Cloud giants wove clouds into fabulous garments.
Storm giants forged weapons of lightning and thunder.
Hill giants being simple creatures slew the animals and made their bones into great works.
All the while the mountain giants laughed.
The stone giants grew rich and the other giants grew jealous and fighting broke out. But still the stone giants Dig their tunnels hungry for even greater wealth. They found only death. Within the reaches of the earth the primordial balancer slept. a being trapped long ago. but still it slept the giants greed still took hold of their hearts for the creatures had skin of shiny smooth metal with the hardness of a diamond it was beautiful and terrible to behold the stone giants hauled the wondrous creature from the deep mines to show its brothers. a great congress was called and the richest of all the giants came to see this new treasure, save of course for the mountain giants.
It is said the ancient energy of the giantheart lulled the torpid beast from its slumber. The giants battled but had grown soft with their greed and were almost nearly destroyed. as was the giantheart only the savage warlike mountain giants had the strength to battle the creature back down into the earth and bury it again.
What energy the wildheart had left turned away from the giants as the giants had turned from it and from that point on the children of such were small and puny dubbed dwarves were enslaved the the greedy giants and for a time lived under the yolk of their brutish ancestors until the great revolt the dwarves learned their lessons well and fought back against their giantish ancestors . The fallen giants wishing to regain the favor of the wildheart were cruel and warred with these dwarves but the dwarves learned how to fight back but were still thrown from their homes.
The other giants eventually died off save the few remaining mountain giants. But the dwarves lived on wandering the cold hard lands of the world finding shelter wherever they could. still they lived on and in their own ways thrived and prospered. their hearts still having a portion of the greed they built their homes where their fortunes might be found.
Storm Dwarves
Passionate and proud. these dwarves have thunderous voices like the storms they live about.
Fire dwarves
Fiery and creative the fire dwarves live in volcanoes wielding flames like other wield tools and weapons. Pyromaniacs and anarchists they personify the chaos of fire.
Frost Dwarves
Cold and dispassionate. these dwarves hearts are as bitter and cold as the glaciers they call home.
Warf Dwarves
Ocean dwelling cousins of frost dwarves these dwarves call the frigged waters home and craft cities out of long dead coral mountains on the bottom of the ocean.
Hill Dwarves
Wild and savage the Hilldwarves are a barbaric people surviving on raiding and pillaging as much as agricultural practices.
Stone Dwarves
The most common of the dwarves the stone dwarves carve great homes out of their stony domains and work metal. pretty much what one might expect a dwarf to be like.
Blackstone Dwarves
Similar to Stonedwarves only driven from their underground home by an undead plague they are adapted and have come to embrace living on the surface world.
(Any ideas for alternate racial traits?)
I somehow imagined Stone Dwarves as normal ones, Blackstones as Duergar, and Fire Dwarves as Azers.
Anyway, I think the Advanced Race Guide should give a hand in coming up with some alternate racial traits for these Dwarves.
While I do not have specific suggestions for alternate racial traits, try the naturalist approach.
Look at this new species and figure out what does it NEED to survive? What traits would it have evolved? What does it eat? Maybe one variety had no choice but to eat poisonous mushrooms, and so the surviving lineage must have evolved an immunity to the poison.
What kind of eye sight would be required? Would fire dwarves still have dark vision if they're always hanging out in volcanic areas with fire lighting up the darkness? Maybe they now only have low-light vision.
Get on your best Attenborough impression going and look at the situation like a biologist.
