[list][*][u][b]Name[/b][/u]: Illyasviel von Einzbern
[*][u][b]Age[/b][/u]: 18 
[*][u][b]Gender[/b][/u]: Female

[*][u][b]Personality[/b][/u]: Illya is a cheerful, friendly girl, quite good at retaining a positive attitude even in the face of her father being injured. She's also quite lonely, though, given being raised apart from almost everyone in the world and even now looking and sometimes acting a lot younger than her peers. That, and people would do well to remember that the cheery, friendly girl was raised by a former mage killer as well and has learned [i]quite[/i] a bit.
[*][u][b]Skills[/b][/u]: Well, she's multilingual. And cute.
[*][u][b]Abilities[/b][/u]: Aside from effectively infinite mana and command seals that can control any Servant--even one as much of a handful as Heracles might be--Illya has Mystic Eyes of Binding. She can also turn her hairs into individual magical constructs to do battle with another magus, which certainly wouldn't work for someone who can't afford to stick as much magical energy into absolutely everything as she does. 
Now, she of course has the benefits of being an Einzbern alchemist and all that entails, but Illya does also have the remarkable ability to become a cup. Her immediate family would probably not approve of this, or using the Dress of Heaven.
[*][u][b]Brief Backstory[/b][/u]: In comparison to the world of Fate/Stay Night, Illya has had a much more cheerful upbringing on account of not having dead parents, and even spent some time being raised [i]outside[/i]  of the Einzbern castle. Something that somehow lead to having a younger brother.
Needless to say, though, she is still the Einzbern Master for the war and highly dangerous to boot. Leysritt and Sella came out of the attempt to abduct her for the most part unscathed.[/list]
