  • End of the Batrachi and Giants War
    The conflict between the Batrachi and the giants of Ostoria comes to an abrupt end when the ice moon Zotha falls from the sky devastating much of the lands within central Merrouroboros. A large fragment of the moon carves a gorge so deep between the four Inner Seas, they merge together to form the Sea of Fallen Stars, an event the sarrukhs remark on as a "changing of the stars". Severe earthquakes rocked the region for weeks afterwards. The crystalline batrachi cities, though reinforced by magic, were unable to withstand the incessant aftershocks. Within a year, the Batrachi Empire had fallen into ruin.

    The impact of the moon threw up a thick cloud of dust into the atmosphere obscuring the sun for seven years. Without the sun, plant-life began to die out across the land, soon followed by the herbivores and finally the carnivores. Only those peoples possessing great magic or divine protection survived the mass extinction. »

  • The Dawn Ages / The Time of Dragons
  • -30000 DR to -24000 DR
    The empires of the creator races fade into memory, ushering in the Time of Dragons and the Time of Giants. Individual dragons and dragon clans rule large swaths of territory and battle with their rivals for control of the lands, seas, and skies. During this period of devastating warfare among the dragons of Faerun, isolated pockets of formerly dragon-ruled territory fall under giant control. Over time, such giant-ruled kingdoms come to threaten the hegemony of dragonkind, leading to great battles between giant kingdoms such as Darchar, Grunfesting, Helligheim, Nedeheim, Ostoria, and Rangfjell, and dragon-ruled realms such as Argissthilliax, Caesinmalsvir, Darastriverthicha, and Tharkrixghontix.

    This time of conflict plunges Merrourboros into a four-thousand-year-long "dark age". The fey are particularly active in Merrourboros during this period, using their small size and potent magic to aggrivate the wyrms at every opportunity. »

  • Merrourboros, circa -27,500 DR

    For the next four thousand years a succession of dragon empires dominate central Merrouroboros. Notable among these empires is the Demesne of Atranjikhera, ruled by the desert landwyrm Argissthilliax. The wasteland empires's rule was harsh.

    While the empires of dragonkind waxed and waned, the giant tribes united once again and spread to cover most of northeastern Merrouroboros. The Colossal Kingdom as it comes to be known is divided into several regions, one for each jotunbrud tribe, Vilmos, Nicias, Ruk, Ottar, Masud, Obadai, Dunmore, and Lanaxis. Voninheim is constructed as the Ostorian capital. »
