And who might you be?

So I have the Guild Wars soundtrack...and I just purchased the special edition one through direct sound (not obessed, I swear! >_>), and I noticed on the CD that there's a song called "Tasca's Theme".

Herein is my question, I've never heard of this woman...EVER. Anyone know who she is in relation to the game? I'd say shes fairly important, given she has a song named after her....but im merely speculating.

Heck, I know that name... I think I heard it in "Tasca's Demise," an area in the game. Probably a historical figure in GW lore
