Maybe mysterious isn’t a good word, but the main character, whose point of view the story is in, doesn’t really know her or a lot about her.
This mysterious character is female. I would compare her - kind of - to the tenth doctor in [name_m]Doctor[/name_m] Who. She’s kind of eccentric, but very smart.
EDIT: Sorry I didn’t put this information! The setting is modern day. If it helps, I’m looking for an unusual but classic name.
I don’t know if that’s enough to go on…is there anything else you can tell us about her? More about her personality, her tendencies, her appearance; anything, really.
What kinds of names are you looking for: unusual? Somewhat common? [name_f]Fantasy[/name_f] names? Old fashioned or modern?
There isn’t enough information here to think up any names.
I’m not really sure what kind of style/time period you’re aiming for but how about:
[name_f]Xenia[/name_f]
[name_f]Hester[/name_f]
[name_f]Maeve[/name_f]
[name_u]Vesper[/name_u]
[name_f]Ariadne[/name_f]
[name_f]Athena[/name_f]
[name_f]Indira[/name_f]
[name_f]Evanthe[/name_f]
[name_u]Raven[/name_u]
[name_f]Beatrix[/name_f]
[name_f]Zinnia[/name_f]
[name_f]Minerva[/name_f]
[name_u]Ezri[/name_u]
