Elva Dementius

Name: Elva Crow Dementius
Species: Semi demonic, semi vampiric (yep, another one)
Age: N/A
Gender: Female
Appearance: Elva is a non-identical twin of Teran Dementius, with gold hair streaked occasionally with a paler colour. Her eyes are more cat-like than Teran’s, although they are the same golden colour. Unlike the other female part demons, Elva’s built is stocky rather than slender. Her face is mainly planes and angles, along with the usual pointed ears. She does, also as usual, wear a silvery cloak along with a black shirt and trousers. She normally has a bow slung across her shoulders and a quiver tied to her belt.
History: Elva and Vrael what you could have called childhood sweethearts, or at least as close to as demons got.. The two archers had trained together in their early years before Vrael had been thrown from the dimension during one of his father’s outbreaks of fury.
After that time, Elva still nurtured her feelings for Vrael, getting an occasional letter from him. When she found that he had become semi vampiric, the demoness became determined to also acquire the half vampire blood.
Elva also shared Teran’s views on the rest of the Roth-Mercian clan, although she never told him about her love for the silver haired Mercian.
She has only just recently arrived in the Earthern dimension, and is determined to find him again.
Powers: Elva has the normal powers for a demon, meaning that she wields a pure magic (coloured silver). She is also fairly accurate with a bow and arrow. However, she is vulnerable to silver and holy water.
Personality: Elva is very good at playing two different roles. In front of her brother, she acts as he sees that a demon should act (mainly evil), but she also has a more ‘feminine’ side, notably when she shows some vague degree of compassion and sympathy.

I sense big climatic rivalry/love battles between Elva and Alba.
Like, it's really tingling.
