She's Eowmaeg, daughter of a wealthy merchant. She's always dreamed of adventures and she has been practising for a long time. As she matured to adulthood she made her father clear that she is going to go seek her fortune no matter what (she even cut her beautiful hair short). As a concern father, that merchant used his connections to have dwarven runesmiths do her a custom fit best possible armor that money can buy (well, best those runesmiths can do and fragile young lady can carry) and bow from elven masters (that is actually +2 bow with ability to see in dark, elves keep their best stuff in the family). As she is ready for journey she thumbles to this band of adventurers that are willing to take her with them. Actually they have been rewarded handsomely for taking care of Eowmaeg. So she's kind of in a safari with lifeguards at side (she doesn't know that though). I'm particulary happy with sword's handle.
