House Eyllisundinaea was in ancient times one of the greatest and most renown among elves, many of their members were famous Oracles, Seers, or Forest Knights. They were patrons of artists and musicians, their wisdom and advice was sought after when new settlements were planned, and the location was decided by them. Two of the Feyborn bloodline became once Queen of the elves.
As time passed by and the old elven gods grew weaker the House became rumored to deal with otherworldly beings, devils, dragons, ghosts, and that many of them were witches themselves. It was already known that feyblood is strongly running in their bloodline, the snow white hair of the Eyllisundinaea sons and daughters was a proof to this. Despite being respected the rumors grew and escalated, the fact that while most of them were untrue didn't keep their enemies from spreading them to damage their prestige further.
Still, the family that to common men is known as House Feyborn remained strong, and even revealed its true ties to witchcraft, as indeed, House Eyllisundinaea had many witches and warlocks in its ranks.
As elven generations passed the family became more and more distant of the elven society, and created diplomatic ties with nearby humans and started to trade with dwarves. It was about this time when they were cursed by the then royal family of the elves on forged evidence of turning against their own kin and massacring an elven town. In truth an ancient rival House got rid this way both of its enemies in that town and also got House Feyborn exiled. The curse itself was simple but considered a death sentence for the family as the result of it was that only females would be born to the family, thus sooner or later eradicating the bloodline.
Those fools didn't consider the wisdom and foresight of the white haired witches though. House Eyllisundinaea withdrew to their most outlying lands and started constructing a great fortress and city, the Black Citadel as it got later called. The family also declared to be from thereon matriarchal and thus ignored the curse the best they could.
The change in governance to a matriarchy and the emergence of the Witch Queen's faith that the family converted to aided much in the changes that resulted in an amazon-like society that formed around the Feyborn family in the Black Citadel. The current family has many members and side-branches, the main family that rules the Black Citadel has five members.
Head of House: High Mistress Rhyliannah Sylessin Eyllisundinaea (elf)
Her children: Lysanna Rhae Eyllisundinaea (elf, heir), Laeriel Marille Eyllisundinaea (elf), Mayrien Cyrivelle Eyllisundinaea (half-elf). and Maeve Sylessin Eyllisundinaea (youngest child, half-elf)
Rhyliannah had all her four daughters with different men, they all resemble her the most though, and all have snow white hair.
Black Citadel: This is the "capital city" of the Feyborn family, its name comes from various sources. The most obvious is that the fortress and city walls are made of a dark, almost black stone. Superstition and rumors made it get called that also because the fact that it is ruled by witches, and for many men it represents a fear of what may happen if women come to power. The city flourishes currently, nearby territories are owned and protected by it, it is basically a city-state what gives refuge to those who accept their laws and want a new life without their new neighbors looking into their past.
The citadel formed a culture similar to the legendary amazon one, females rule, their name is inherited by the children, and due to the influence of the witches those with arcane or divine powers are also above the average people. A commoner male wizard or warlock is about as much worth in the society of the Black Citadel as a non-spellcaster noblewoman. The Black Citadel does keep male slaves that are gathered from battles, but these always had the right to rather take the death sentence, and some of them do regain their freedom if proven worthy.
Darksprite Forest: This forest is what protects the western borders of the Black Citadel, it houses fey folk and hags loyal to House Eyllisundinaea and its laws. Rumors say it also houses a clan of neutral werewolves of elven origin.
Iron Hills: The Iron Hills is in fact a smaller mountain with a lake and a rich mine on its top. The river from the lake comes down as a waterfall and is known as the Iron River. The river flows through Black Citadel and is the primary fresh water source for the city.
