Her father decided to imprison her for eternity instead of kill her. However, Silena was not happy with this decision and she ran away soon after. Since then she has travelled the human world, witnessing the creation and destruction of many of the great empires & civilisations. She is spoken of in legends as the Ancient Wanderer. After saving one small country from invasion single-handedly, they now worship her as a goddess.(Cont.)

She has the powers of her mother, but never uses them as:
1) She's a bit afraid of them
&
2)She thinks that if she uses them, her father will find out where she is. Unknown to her, her father has been keeping track of her since the day she ran away. However, she has learned ice magic from the people she has met on her travels, and is said to be the best Ice mage in the world. Also, she is extremely skilled in mechanics and her inventions are decades, maybe centuries, ahead of the humans. Her inventions are a mix of technology and magic and include her wings (currently folded,the blue is a sort of plasma) and her sword (which also functions as a staff and a gun).Despite living in the wild, she cares a lot about her appearance (the halo is not real, it is actually attached to her head) She is worshipped as the goddess of Winter and Wolves, as she has a strange natural empathy with wolves and they will always do her bidding. (Cont.)

P.S. THE TITLE IS SUPPOSED TO BE 'SILENA', NOT 'SEVERA'
As her mother was a human and she has spent most of her life among humans, she is much more friendly to humans than her other sisters. She is a generally serious person, but can become emotional when angry. She has a fascination with shiny things, especially precious stones and if she finds or is given (she doesn't steal!) a gemstone, she will store it in a special place of her's where she puts all her precious things, though nobody knows where that is. Though she has tred to, in general, to distance herself from her family, she still keeps in contact with Serpia (by wolf) and whenever she meets one of her sisters (rarely) she is quite friendly to them, as long as they don't mention her father or her mother. She likes Jelly-beans.

The disign seems cool and the backstory is really great. Though I've tried several times to stress that the mother should not be human or goddess. However, I'm kinda impressed with how detailed the story is and I could almost see it working. I'll try to keep an open mind.
