OLD KJELDOR
Kjeldor was a nation on eastern Terisiare during the Ice Age of Dominaria, occupying the general area of the old country of Argive. During the Flood Ages it merged with the lands of the Balduvian barbarians into New Argive.
Kjeldor was founded 500 years prior to the casting of the World Spell by Clan Pearl and Clan Emerald, two of the five clans of the kingdom of Storgard. These two clans had left their kingdom for they thought, correctly, that it would soon be caught under the ever-growing ice caps. Kjeldor is named after Oriel Kjeldos, the old leader of Clan Emerald who died on the journey from Storgard. Her descendants became the royal family of Kjeldor.
Generals like Jarkeld and Márton Stromgald brought the nation great prestige, but over time this dwindled. The effectiveness of the nation was hampered by the fact that all decisions had to go via the monarch him/herself. A council was created as a way around this, but the various groups in the nation tried to dominate it, which led to a split in the council and further splintering led to the factionalism that plagued the late Ice Age Kjeldor.
By 2934 AR Kjeldor was weak and decentralized. Royal mage Gustha Ebbasdotter had to rely on willpower and charisma to keep the various factions of wizards in control (and even that failed at times, as the Zurans split off from the general order), the nation's military was split up into many different groups and the king's policy was mainly dictated by the merchants of Krov.
This all changed when Avram Garrison, the unofficial leader of the military, became disgruntled over the state his beloved Kjeldor was in and the fact that King Darien would not unite the military and make Garrison its' general. Aided by the necromancer Lim-Dûl he formed the Knights of Stromgald and attempted a coup. The coup failed and the Knights were turned into zombified minions of Lim-Dûl, but the cleansing of the military top allowed Darien to take firm control and to merge the various factions into one army led by General Varchild. With Lim-Dûl as the common enemy, Darien also managed to rally all the merchant and mage factions behind him and even made an alliance with the Balduvian barbarians with whom Kjeldor had been in conflict for generations.
After the final battle against Lim-Dûl, the alliance shattered and Kjeldor slumped back into what it had been before. Varchild herself even went rogue and formed a militia against the Balduvians. At the same time Freyalise cast her World Spell, which ended the Ice Age but also caused the rising of the sea levels that resulted in flooding and a change of climate that brought new diseases along with it. Yet in this time Jodah, Archmage Eternal of the School of the Unseen, who had also been an important player in forging the original alliance, managed to convince King Darien and Balduvian chieftain Lovisa Coldeyes to stop the fighting and work together to help their people through the trials of the Flood Age and the brief return of the ice brought on by the Cult of Rimewind. This cooperation would eventually result in the merger of the two countries into New Argive. The royal house of this new nation was created in the marriage of Alexandrite, daughter of Darien, and Lothar, son of Lovisa Coldeyes.
The main power of the kingdom lay in three city-states: Kjeld, the old capital and location of the royal summer palace, Krov, the new capital during the latter days of the Ice Age and Soldev, an almost independent city located where Storgard had once stood. In the Kjeldoran hinterlands lay only small villages of which Breway, Jarka, Freyta and Mikkel were named.
The story Reprisal from the book The Colors of Magic mentions a Lord Rotchild based in Jornstad, as the ruler of eastern Kjeldor. It could be that the dynasty of the Kjeldos family was interrupted for a while, or that eastern Kjeldor was also semi-independent like Soldev.
NEW KJELDOR
As of 4562, King Darien XLVIII rules New Argive, ruling from the recently redeveloped Kingdom of Kjeldor on eastern Terisiare.
Darien, King of Kjeldor began a quest of unification and purification unlike anything in the history of Kjeldor, resulting in Kjeldor becoming a beacon of power, justice, and salvation. By discovering and deepening the connection with Nyx using the legendary Godsend, he was able to harness godlike blessings for his people as well as establish a bond with the angels.
A paranormal realm associated with dreams and the subconscious, Nyx is a literal and proverbial night sky where the gods dwell. Nyx is so closely tied to the plane's deities that, whenever they manifest, where they should be shadowed they instead display the glorious starlight of the night sky. Dreams are seen as gifts from the gods, and so are enchantments, due to their connection with this realm; whenever mortals sleep, they are said to be "visiting Nyx". Tales of the gods can be seen played out in the constellations. When Godsend is present at Nykthos, Shrine of Nyx, humans are able to channel the energies of the gods as well as communicate with the angels.
