Era beginning/end
The 1000 year-old period of darkness that affected the Old Folk and their technology.
After a particularly brutal invasion by a group of Indagarians, the Great-Library of the Old-Folk was burned down in 597,949 DE. With most of their information lost, and attacks increasing daily, the leaders of the Folk agreed to shut down their computers to preserve what little energy they had left and use it to make more weapons. During this period many leaders, whose names are unknown, where selected. Almost all of them died in battle. The Folk were desperate. Their Doors were shutting down, and they were running out of Nuclear-Magic to make more weapons. The Indagarians kept attacking, with defenses weakening daily. The Folk sensed something horrible coming in the future. So they decided to make once last effort at their survival. After a thousands years of fighting, they set to building a massive building later known as the Black-Tower. It is unknown what the Tower was to be used for, but it was completed by the machines after the Folk vanished.
