Rheulgard is a region long left alone by humans, for it remains one of the most remote and least accessible realms in Cerilia. The sidhe never lived her in numbers, for most found the woods and lakes and streams too dark for their liking. When the remaining sidhe, over the course of several centuries, retreated into Coullabhie, Brechts from the Basin South region slowly migrated south across the Mountains of the Stille Wäthcer. Eventually several local kingdoms (cantons) emerged, but they generally stayed on peaceful terms with one another, not least because they were separated by barriers of water, wood and rock. Except for a few brief attempts at domination by this canton and that, the land has never been unified. So much so that ‘Rheulgard’ is just a term used to refer to the region. Citizens of the Canton of Unbrau would be very offended if you suggested that they be subjects of the kingdom of Rheulgard – they think of themselves as Unbrauer.
In the later years of the Anuirean Empire, when its rule became oppressive, certain freedom loving Brechts fled to Rheulgard. Their influence brought a greater degree of cultural identity to the area. And when Brectür finally rose in rebellion the descendants of some of the same refugees returned to the Bay to carry the banners of freedom. These events brought Rheulgard more fully into the rest of the Brecht world, and helped cement its bonds to the realms along the great bay, but natural barriers has prevented the influence from becoming overwhelming. As a result Rheulgard is still characterized by the existence of a number of independent sub-realms, but they are fewer in number than was once the case, with several smaller cantons joining together into larger ones.
