I don't know if this will make it into the character sheet, but when I did my write up for her, this was her background.
Hook
Stronger than her size belies, Zidi is touched by fey magic. Though hunted by minions of her gremlin godmother, Zidi hopes to use her powers to defeat those who think their size and power mean they are not accountable to the small and weak.
History
When Zidi was only a toddler the armies of a dragon tyrant razed her mountain village. She was saved when gremlins scrounging for salvage found her struggling to dig herself out of rubble. Their dark matron Granny Allswell fostered young Zidi in the caverns of her home in the Dreaming. She taught the halfling to cavort and wrestle with her other little children, but unlike so many other foundlings Granny brought in, Zidi never gave in to fear during the wild underground revels and so did not transform into a gremlin herself.
Granny made use of her by sending Zidi on missions to steal shinies and cuties from the Waking realm, and every time she was rewarded with a boon of strength. Over time Zidi grew uncomfortable with the fear she was sowing however, so one day she ran away and has never returned.
Personality
Zidi's the kind of person you just can’t not like, except that sometimes she is a little overeager and too inquisitive. She’s one of those lucky souls who are truly happy because they know what they’re doing is right, and they enjoy doing it. Zidi lives life intensely but kindly, laughing and crying with those around her. She sometimes seeks out communities of halflings, gnomes, goblins, and kobolds where she grasps for a simple life, yet she never stays long, fearing the pursuit of Granny Allswell’s other children.
Goals
Zidi finds herself drawn to conflicts between fey and the world of mortals. She feels a supernatural strength growing in her (right now she can lift 1080 pounds!), and she wants to draw it out by challenging herself and facing ever greater foes. One day she hopes to find the dragon tyrant who killed her family and do some “draggin” of her own: wrestle the monster to the ground, tie it up, and bring it to justice.
