Chronicle of Holo continent
The ninth edition by Triarius Testis
In a world full of mysteries and wonders, great colourful dragons steered seas of stars. Among these stars, there was one that lit exceptionally brightly. Its light, like a beacon, lured the gazes of many onlookers, even those of not this world. One day, an emerald dragon decided to take a closer look at this shining star. Smaragdos was his name, the powerful, sagacious, and benevolent lord who gifted me the history of this world.
He travelled ages to reach his objective, to witness two worlds rotating the star. Twin worlds, one green and one blue, Soror and Frater, accompanied by a moon named Peregrinus, were enveloped in the star's light, so bright he could barely see. When the great Dragon approached the twins, his heart was filled with grief, for one of the two siblings was gravely ill, and no cure existed to relieve its pain.
Frater, the world where our continents lies, was infested with disasters and evil. The children of Soror were crying for help. The heart of the Dragon is as big as a sun ached for these unfortunate souls. That is when the decision was made to aid those who could not help themselves, so he descended from most northern peaks to raise a kingdom that might face the threat.
The Era of Chaos
There are many kingdoms in our realm. They appeared and disappeared constantly over the era of chaos. Most of them were powerless before the threat of calamities that occurred now and then, and every one-hundred-year map had to be redrawn. Taking that into account, there are few historical records before the foundation of the Mivell Kingdom. So little that we have was inherited from the Arcanum Empire, which tells us only of a few events up to the 12000 Era of Chaos (E.C.). An empire that tried to consolidate all the continent's resources to fight the calamities. They created many artefacts and built vaults, some of which still survived. They even managed to subdue lesser calamities. But even they could not survive the great calamity that comes every thousand years. At 11000 E.C., the star calamity, of which no record, except for the name, remained, obliterated the Arcanum empire. It reached the heart of the continent, the Empire's capital city, where Dragon's Dominion capital is currently located. It burned everything to the ground, including all citizens, structures, and records. Creating a crater the size of a country. This crater is now known as the Great Valley.
