The Duchy of Acromton contained the province and town of Acromton and the province of Damescross. Traditionally the Duke of Acromton was known as the "Duke-Crossguard" as they guarded the bridge to the Isle of Damesear.
History[]
The duchy was created as an appanage by Grand Duke Aldres II Silmuna for his second son, who would later be known as Duke-Crossguard Marion Silmuna.
The Duke-Crossguard would later marry the the Duchess of Rubenaire Kylia I síl Rubenaire, who, under the cognatic rules of Lorent, allowed women to inherit on equal grounds as men. The two duchies would be intertwined in union under the House of Silmuna until the death of Kylian II Silmuna.
His sister Duchess-Crossguard Kylia II Silmuna would inherit the two titles but had also at the time been wed to Marion I síl Rubenaire, a member of the original House of Rubenaire, which would return the Rubenaire to its founders, and bring the Duchy of Acromton with it.
Despite defecting in the Fourth Lilac War, due to the House of Rubenaire's support of the House of Silmuna for most of the Lilac Wars, the Duchy of Acromton was ceded to the Grand Duchy of Wex, under claims that the duchy was to return back to the Grand Duchy of Dameria and if that was not possible (as Dameria was dissolved by Wex), it was to return to the holder of the imperial throne (also Wex). Rubenaire was rightly outraged with this, and since then the Dukes of Rubenaire also claim the title of Duke-Crossguard, a title nominally held by the ruler of Acromton.
