Hello! I'm new to FFXIV but this is my concept so far.
Altani Qalli was a message runner of her tribe -- she would take missives to and fro between the tribes which the Qalli were allied to (temporary or no) or had a neutral rapport with. As she traveled, she would gather stories told by the different Xaela tribes and would embellish these stories of hunting, adventuring, and honor into fantastical tales she would entertain others with. Her life was traveling, storytelling, and song -- so it was no wonder she fell into the bardic lifestyle.
Befitting her Qalli background, Altani speaks with a musical lilt, and her sentences seem to be formed for beauty and an appreciation of sound. She enjoys listening to others tell their life stories and their adventures -- and she enjoys entertaining others with what she's come up with in turn. Of her past beyond the obvious, she's very brief. If she does bring up bits and pieces, they're said in the same vein as her obvious half-fabricated stories, so it's difficult to say if it's the truth or not.
Thaaaat is all I have, and I am treading lightly because this is a BOATLOAD of lore that I am still getting into as I am but a wee level 34-ling and I don't want to step on anybody's toes.
