Believed to have origins in both the Malkavian and the Toreador clans, the Daughters are very few in number. As their nickname "Sirens" suggests, the Daughters are known for their ability to deliver emotions through a form of song. They have a unique discipline called Melpominee (after Melpomene, muse of tragedy) that does just that.
Not much is known about the Daughters of Cacophony as a whole, only that their particular bloodline avoids the nightly troubles of the Jyhad. Since their numbers are so few, organization is questionable. Interestingly enough, all members of the Daughters of Cacophony seem to differ from heavy metal rockers to opera singers.
Currently composed mostly of women, the Daughters practice Melpominee, a Discipline which allows the Daughters to invoke strange effects through singing. The Daughters are the choralistes par excellence of the undead, and hosting a gathering of them is worth high prestige for the Toreador. And although it is mostly female vampires who number among the Daughters of Cacophony, male members of this bloodline do exist, although they are uncommon and usually regarded as oddities.
Some Kindred have been witness to small assemblies of Daughters who perform songs of haunting beauty or frightening timbre that leave their audiences... moved. It has been noted by observant Kindred more than once that even in the most impromptu performances, all Daughters present seem to know exactly what will be sung in addition to all the verses.
In line with their particular penchant for music, a Daughter of Cacophony will constantly be able to hear an inner music flowing through their mind. However beautiful this music might seem, it also impedes them by serving as a constant distraction, making it harder for the Daughters of Cacophony to perceive things around them. The Daughters call this melody the "Fugue".
Some Daughters completely succumb to the Fugue, becoming what the Daughters call "Banshees". Unable to perceive anything but the song within them, they are unpredictable and often violent.
It stands to reason that this weakness could give credit to claims of the Daughters being a clan of Malkavian offshoots, seeing as they are permanently deranged with auditory hallucinations.
