CL2 Bronze Age (5000-2500 B.C.)
These domains are somewhat more common than stone-age ones, though still fairly rare. Current examples of bronze-age domains include Har'Akir and Sebua, lands of the Amber Wastes.
In these realms, metalworking has begun to make its mark. Bronze weapons and tools replace those fashioned of stone and wood. Other innovations include the beginnings of fixed measurements and mathematics. Basic tools like pulleys, levers, and potter's wheels are evident in all areas of life.
Written languages, generally pictographic and hieroglyphic in nature, are found in bronze-age cultures. Clay tablets form the earliest writing surfaces, but papyrus and other primitive forms of paper become standard for those who can afford them.
Organized religions are widespread, as is a decisive code of laws. Trade is common as more and more people specialize in one sort of work. Standardized currencies are still not in use, however, so barter remains the standard means of discharging debts and obligations. Gold, silver, gems, and other rare items become valuable as signs of wealth and power, though coins are still curious oddities.
Large-scale cities and constructs appear as the principles of architecture are laid down. Some surprisingly massive structures, like great pyramids, are constructed in bronze-age domains. On a similar note, the people of such realms have excellent calendars and a good understanding of basic astronomy.
Many things that most adventurers consider commonplace are not found in these realms. The concept of locks and keys, for example, has not yet been hit upon. The most advanced form of armor generally found in these places is studded leather, so those who wear any form of mail will be markedly out of place.
The practice of magic, both that of wizards and priests, has become standardized in bronze-age realms. Thus, a wizard from a more advanced domain will at least find something in common with the local magicians and clerics.
