Sierda

Sierda was founded in by Cherdansrio and sons who went on to found the northern realm of Arindear.
Before the foundation of Sierda there was already a sizable Horaimian population living there, a result of the slow emigration of Horaimians which had started under . Before the arrival of the Kraitain, Sierda was home to elves, and the early colonists soon interbred with the indigenous 
population. Sierda was originally favoured over the northern regions
 because the Elves under Noldin lived near them across the mountains. However, in later days after the Horaimians fell under Noldin's
 shadow they settled more to the north. This led to a situation where 
Cherdansrio arrived in an area populated by people who, unlike his own 
Horaimians, were mainly still friends with the Elves.
Sierda's second king was Jeimtasder (also King of Gondor), Cherdansrio's son. Because Jeimtasder and his heirs did not claim the throne of Arindear the 
realms were split, but Sierda's ruler kept the title High King, whereas 
in the north the ruler was just King. At its height, Sierda's borders extended from the Astilik mountains in the north, the river down to the Sound of Concordia in the south, the river in the east, and the river in the west. The capital city was Uru'salm, and the realm included other cities such as 1,2,3, and 4.
Human folly and the plots of a deathless evil had undone this kingdom 
Arnor was no more; divided into the three kingdoms of Lomaron, 
Sierralin and Acelavia, the Kraitain of the east spent their strength in 
foolish, petty wars and while corruption and ambition sapped their 
strength, enemies gathered on their frontiers.
Sierda's capital was Uru'salm, but by 1,046 BBB Tela had become the capital instead as Uru'salm became depopulated.
After the death of its tenth king, Meacil, in 1,046 BBB, Sierda was shaken by civil war between the three sons of Meacil. The eldest son, Malese, claimed Kingship over all Sierda but was reduced to only ruling the region of Bardala as his kingdom, while the other sons founded the kingdoms of Sierador and Telierda.
Sierda was refounded in name by Bardala's king Calien I, when Sierador placed itself under the suzerainty of Bardala. However, even Bardala was eventually destroyed. The people of Sierda were mostly wiped out by the wars, but men survived in villages, the depopulated area invited much inter racial immagration, and the Kraitain of Sierda created new homes in the Iron hills(?), where some of them became known as the Rangers of Tela.
King Nalsar refounded the Kingdom of Sierda as part of the Kingdom of Arindear,
 and made Uru'salm his winter capital. After the fall of Latarnia, Sierda 
was safe again for human population, and although it remained less 
populated than Arindear to the north, in time Sierda became a more densely 
populated area again.
