Semiramis is the first and only daughter of Quelaag and Etherus Darksoul. When Semiramis was concieved, her father was banished against his and her mothers will and so she grew up in the Demonic Ruins of the Kingdom of Izalith with her mother who made sure to tell her the stories of how her mother met her father and the aid he gave her before the fell in love with one another. He helped with her aunt Quleean, for she was blind and unlike her mother, she was also an albino half spider demon and had trouble fending for herself and relied on her mother and her father to keep her sustained by feeding her humanity from the twisted creatures that were cursed along with everyone else. When she got older, Semiramis would feed her aunt and spend much time with her just telling stories and helped make her feel closer to the kingdom from her solitude away from the kingdom Quelaag now ruled.

Like her father and mother however, Semiramis can have a mean streak and has been known to attach and kill creatures for no reason at all other than she wanted to be entertained. She may seem like an innocent survivor of the plague that seemed to have caused so much chaos and ruin but like her aunt and mother, even her father, she is a creature of demonic chaos and has the ability to shift her eye color based on her emotions. She also torments the lower beings who still seem to have some of their sanity and tortures them drinking their blood and bathing in their screams. She can be kind or she can be cruel but can not deny a darkness soaking in her soul from the union of her mother and father as she had developed in her mothers womb.

She also has a demonic form in which she sprouts wings and has a shadow pet that wraps around her and has sharp teeth and red eyes while she has two horns that take their place on her head, her right arm forms into a elongated blackness with three claws, her eyes shift to flames and her face looks like that of a cracked porcelain doll. She also has a cluster of glowing red crystals that emerge in the center of her chest and she gives off a faint reddish miasma that poison's any who breathe it in and uses her shadow pet to rip souls from their husks and devour them.

Semiramis is now 17 years of age until April 22nd and as such her mother found that she had taken on a leadership role quickly, it coming naturally to her like breathing from her mothers training and the stories of her father and how he ruled. Upon finding a tome of magic spells her mother was determined to re-unite with her beloved husband since it had been hundreds of years, time working differently in the Ruins. As such her mother was successful in her attempt to transport to the realm of her husband.

In her absence Semiramis took over the Kingdom of Izalith and ruled with two different extremes, she could be cold and cruel or she could be kind and caring reverting to whichever she needed with the subjects turned into demonic creatures that would either try and attack those in the Ruins or those who sought aid. She also resumed taking care of her aunt and making sure her grandmother and aunts kept the same flame that lead to their demise and fall of their kingdom constantly burning where they were kept in solitude much like her demonic spider aunt Quelaan.

Then the day came when she received word from her mother after her long absence in hope that her mother was able to find her father, that her father was getting married to two wives and they were invited to the ceremony. Semiramis was then transported by the same magic by her mother and joined her as they made their way to the ceremony, meeting her father for the first time.
