Exact details on what transpired next are scarce, but I have ascertained that at some point during the next two hundred years they decided to use the Vizjerei’s strength against them. To this end, the clans actively sought to capture a mage to do their bidding. Eventually they succeeded in violently coercing one of their captives to help them not only gain control over their transformed clan mates, but to have themselves transformed as well in order to fully drive the Vizjerei out of the Teganze.
Though they were primitive by the standards of the Vizjerei, the umbaru clans held the powerful mages at bay through familiarity with the terrain and sheer ferocity. But this state of affairs could not hold forever. As decades of savage warfare took their toll on the umbaru’s culture and minds, the clans began to search for any means to prevail over their enemies. In fact, they lost sight of anything else.
Their strategy worked, but it was not without its price. They found themselves bound in servitude to the demon Zagraal in exchange for their cursed power (note that I neither endorse nor dismiss theories of a “Burning Hell” by the use of the term demon; it is simply used here in its original intent: to describe a being of malevolent or loathsome origin).
They became furious marauders, driven to raid villages and caravans to sate their bloodlust and procure sacrificial victims for their demonic master. This is also when they became known as khazra, which roughly translates as “demon” or “devil” in the umbaru tongue.
The khazra continued to wage war on humanity, but without a source of demonic power to draw from, they became weak. Despite a slight unexplained resurgence twenty or so years ago, their fury steadily
After years of this terror, their previous brothers, the umbaru of the lower Teganze, sent their sacred witch doctor warriors to eradicate the khazra’s threat to the region. Filled with otherworldly power, the witch doctors cut a swath of destruction through the khazra until they confronted Zagraal himself. In a now-legendary battle, the valiant heroes fought to the last man before finally bringing Zagraal down.
