From 1203 BLC to 444 BLC, the Kingdom of Laeryll was led by Thanyal the Singer and his wife Alythin the Huntress.
The Crown of the Kingdom of Laeryll has the right to designate a portion of the kingdom as 'royal ground', making it their private property. In 360 BLC, Bothandal the Crafter claimed the region between Dathyll and the Thracyll Mountains as his royal ground. Due to the large swampland in this region, the royal grounds were quickly named Laedor Thilis (King's Swamp).
King Bothandal grants mining privileges to specific clans from The Porcupine and the Kingdom of Labar. The dwarven clans are Clan Arad and Clan Bordirūn. The gnomish Estates are the Fiddleflute Estate, the Dabblespeck Estate and the Fuddy Estate. Mining privileges extend to all sites in the Thracyll Mountains that border Laedor Thilis, with the exception of the Chicken's Beak area that is only accessible to His Royal Highness.
Bothandal the Crafter establishes an administrative council for local politics in Pellvyr that is made up of delegates with a strong economic stake in the area. He simultaneously appoints a town constable to oversee security. Since Laedor Thilis is royal ground and falls outside many of the rules and regulations of the Kingdom of Laeryll, which allows the Council of Merchants to set up a parallel legislative structure.
After an incident involving extraplanar creatures on the magic market of Pellvyr, the Council of Merchants agrees that they should appoint at least one True Wizard as a member to oversee arcane matters.
After the death of Bothandal the Crafter, the Council of Merchants comes to an agreement with Queen Galythiel and Queen Morsyana to join the Kingdom of Laeryll as a province. An elaborate legal document establishes that many of the exceptional rules and regulations of the region can be maintained. Laedor Thilis will share Province Keeper with Pothael.
Between 11 LC and 39 LC, the conflict between Galythiel and Morsyana grew into a war that involved the Kingdom of Labar, the dwarves of The Porcupine, and virtually all human territories.
The Council of Merchants in Pellvyr is fully replaced by members of Clan Arad.
In the fortification Khandar's Blessing, Queen Galythiel and the Council of Merchants sign an agreement that sets the conditions under which Laedor Thilis rejoins the Kingdom of Laeryll as a province. The agreement states that ownership of all mining assets remain with the Clans and Estates that operate them at the time of signing and that the Kingdom can tax all trading activities in its province. The Council will continue to fund defenses against the orc tribes from Lorr Tahak.
Within a span of 16 years, a range of orc tribes attacked and raided Laedor Thilis, regularly destroying mining operations and killing workers.
In 80 LC, orcs from the Thurbynn Tribe destroyed Khandar's Blessing during a massacre that killed all inhabitants of the fortification.
One by one, the dwarven Clans and gnome Estates that were still actively engaged in the mining operations of Laedor Thilis decided to leave the area as a consequence of on-going orc raids.
The trading town Beltar was destroyed during a orc raid.
In 724 LC, the Labarean Empire invaded Silimanis as part of its effort to obtain more human slaves. Fighting between the gnomes and the humans lasted for two years, but in 726 LC, Silimanis was firmly under the control of the Labareans.
