History of Risevne
It is thought that the islands of Masalna and Agalmare have been inhabited by humans since around 450,000 years ago; the most ancient evidence of human inhabitation include stone tools made from the volcanic stone of southern Agalmare, dating from nearly 22,000 years ago.
The first known evidence of large-scale, sedentary settlement in the islands is what is now known as the Nurmiara Hills Culture dating approximately from 9,000 BDN to around 4,000 BDN; sites corresponding to this culture have been found across the Nevgasira Plain, farther north along the western coast of Masalna island almost up to present-day Osbane Province, and even on Agalmare. Characteristics of this culture include elaborate pottery, of initially the "clam" and then the "twine-mark" style; extensive use of volcanic rock for tools such as adzes, arrowheads and sickles used for harvesting; firm evidence of coordinated agriculture on the Nevgasira Plain; and eventually the use of bronze artifacts, with locally produced copper and tin from Agalmare, including elaborate bronze goblets.
