Okay, here's what I've got:
[spoiler]Lettice
-----
Gender: Female
Age: ??? (appears to be in her late teens?)
Race: Sylph
Class: Striker
Bio: A mysterious non-human looking young woman whose origins are unknown. All that was known about her is that she appeared from a flash of light, by a lone cottage. It is assumed she was brought from another world. She doesn't remember what happened, but faintly remembers she wasn't alone, when she appeared. She remembers a woman with wings, unlike her own, dressed in an blue attire similar to hers; her whereabout of course is unknown. Lettice behaves in a rather ditsy brashful manner, being very overconfident in her abilities, but never smart on her choices.
Lettice possesses very powerful arcane magic; being able to manipulate fire, gravity and darkness to her liking. Her ability to fly makes her very agile also being able to provide aerial support with her attacks. However, with the absence of her partner, she's unable to unleash her most devastating spells, where here darkness is combined with light magic to create powerful combos. Also her affinity to darkness makes her unreliable in situations involving undead foes. However, having limited fire magic at her disposal, she's able do just fine against them.

I've merely based it off Blue's stats, just changed a few things though. I may need help on what to implement on her powers' effects, though.
