The Night of Lightning
The Night of Lightning was a disaster that befell the city of Helmira during the middle of the Fourth Era. It resulted in the collapse of the White-Gold Tower, the death of Emperor Charles III Viromaro and the prosecution and destruction of almost all ancient magical Orders.
Prelude
Emperor Charles III Viromaro inherited the throne at only fourteen years of age, after his father Charles II Viromaro's brutal death during the Massacre at Summerhal. He managed to successfully destroy the slave revolts in Alcanzar, bringing peace back to the realm. However, ever since he feared another uprising, and tried desperately to increase the power of House Viromaro and the Empire. Funding to the Imperial Legion and the Navy increased massively, and a series of great walls began construction. Lord Sahar, a member of the Helmiran Society of Ancient Magic and Witchcraft offered the services of the Society to the Emperor, promising the possibility of eternal life and invincibility. After seeing a demonstration in the imperial palace of a pig being killed and brought back to life through blood magic, the Emperor became convinced of the power of the Society, and offered a near unlimited amount of funds to gather all the ancient magical organisations from across the Empire. The most secretive of these, the Helmsian Circle, had originally served the Kings of Helmsia during the Second Era, performing animal sacrifices in what is today the Mercenary Bank. Eventually the Circle was convinced to move to Helmira from their sanctuary in northern Attica, where they took residence in the newly built Winterhal Palace.
The Night of Lightning
After four years of living Helmira, collecting ancient scrolls and travelling across Minecraftia looking for ancient artifacts, preparations began for the Great Ceremony, with the purpose of making Emperor Charles III Viromaro invincible and immortal.
From the Imperia National Museum two ancient Helmsian Ceremonial Knives were purchased for 2 million Florynts total. One of which was however lost when the ship that was carrying her was destroyed in a sudden storm in the Senfina Sea. Artisans in Helmira managed to make a near perfect replica of the original blade however.
Knowing the power of animal sacrifices back in the Second Era, the Emperor became convinced by the Helmsian Circle that a human blood sacrifice would successfully complete the ritual. To this end, 365 slaves were purchased at an Alcanzar slave market by the crown, and send to Helmira for the ceremony. During the winter solstice, the ceremony would take place at midnight. The week prior, the plans for the ceremony leaked out to the public, causing small riots across Helmira. The Imperial Legion however successfully managed to squash these.
The White Gold Tower was chosen for the ceremony because of it's ancient connections with Helmsian magic rituals during the Second Era. For a long time the building had been known as one of the strongest places for magic in Minecraftia, evidenced by things like the high amount of ghostly skeleton horses appearing around the building during much of the Third Era.
The night of the ceremony, all 365 slaves were escorted into the White Gold Tower, blindfolded and bound together by chains. The ceremony would consist of the Emperor standing in the middle of the throne room, surrounding by the sacrifices. Then, two members of the Helmsian Circle would begin sacrificing the slaves, one by one, whilst the other members of the Circle chanted ancient spells.
As the floors of the throne room began to red from the blood sacrifices, a crowd of people began storming the Tower, slamming against the locked doors and engaging in fighting with the Imperial Guards stationed outside. This caused the ceremony to be hastened. Eventually, as the last victim was sacrificed, a torch was lowered into the pool of blood, as the last spells were being called out in unison. Then, the knives were thrown into the pool itself.
Once the replica knife hit the blood, a massive explosion tore across the tower, reaching all the way to the top and bursting through the roof and windows. For a minute, the night turned into day, as the entire night sky lit up, which was reported all the way in Lotric and Kreonix. The clouds were blasted away from Helmira, revealing the clear night sky and the shining full moon. Then, blasts of lightning started breaking through the night sky from the tower, first flashing into the air but soon hitting buildings and homes across Helmira, setting fire to several properties. Then, the lightning seemingly turned inwards towards the Tower. With one massive blast the great tower collapsed into the throne room. One more flash of light was seen, and suddenly the building started to burn so hot that people nearby dove into the canals and the Bay of Splendour to escape the heat. Soon the entire ruin of the White Gold Tower sat ablaze. The fires burned so hot and bright, that only by the following night the Helmiran fire fighters and rescuers managed to secure the building. A handful of imperial guards managed to escape the building before the tower collapsed.
Aftermath
After the dust had settled, it had become clear that except for the escaped imperial guards there were no survivors. No bodies, not of the sacrifices, not of the members of the Helmsian Circle and not that of the Emperor were ever found.
Two days later, Emperor Alexander Viromaro, the younger brother of Emperor Charles III Viromaro, was formally crowned in the ruins, in a makeshift throne. In the aftermath, he abolished the practice of magic across the Empire, making all magical societies illegal and heavily prosecuted those caught practising the ancient craft. For the duration of his reign, the Imperial Palace was used as the seat of government, until Emperor Louis Viromaro eventually rebuild the White Gold Tower in a new imperial vision. The ruins of The Tower were used occasionally for important state events during the reign of Emperor Alexander, such as for the weddings of Prince Louis and Crown Prince Amantis. The study and use of magic never regained it's original position.
