Technology/Civilization
"Art, technology, culture, conflict... those who study the past seem to seek but a few distinct things. It begs the question of legacy, to how much of what we do will be remembered." -Lo, Accursed Wanderer
Five-hundred years ago the war ended, the world broken. Already most of the major cities, fortresses, temples, places of enlightenment and power were shattered, and what remained was lost in one final catastrophe that saw the downfall of the remaining mages. The lands were riddled with dangerous magics, the sky was a thick tempest, the seas roiled and churned. All anyone could do was survive. Time healed, and now the lands, though dangerous magics can be found, has greatly tamed. The weather has calmed. The seas are more restful.
What remains are communities that know how to get by in their own unique ways. A village on a plateau that knows how to scale the flat, rocky walls to get supplies from below. A clan living within a volcano have gained a natural resistance to heat and fire. A nomadic group has learned the ins and outs of the poisonous fungi forest. Through evolution, through magic, through ingenuity people have regained control of their day-to-day lives. Still, people have not regained such control, such mastery to build new cities, to slay the most powerful monsters, to make true advancements. Life is still hard, but it is full of hope, wonder, and endless opportunities to make things a little bit better.
As such, there are not many "laws" as they may exist elsewhere. Pretty much all communities will have their basic set of rules and expectations, can develop their own hierarchies, but one will most likely debate on moral and practical grounds as opposed to "it's the law". The world simply hasn't progressed to be so complicated to need multiple tomes worth of laws, and the people may be better for it.
And then there are the remnants of the past. This was the time when legendary magical items, sky cities, clockwork dragons, and competing universities existed. It was a time of opulence, greatness, and wonders that defy logic. The remains are scattered. Anything that was easy to find has been, and no few villages have a remnant or two from the past. Those items that remain to be found are hidden within the most treacherous places to be found. Broken temples buried beneath the earth, old laboratories guarded by fantastical creatures, and the homes of the fallen mages of old still hold technology and other innovations from the past.
