First of all, why does she have a giant sword?

Secondly, do you have any inspirations for her character design? Anything she may be wearing that portrays her personality. I've heard it's best to work on a certain trope, then branch off into natural or unseen branches e.g. she could be an adventurer as a ranger or scout, and therefore may believe that she must be merited to feel she has gained progress.

Maybe her being a goblin(known for their love of gold) could branch off into her being a drifter. That way, she's still an adventurer going to different lands, but she retains traits of goblins obsessing over gold, as she needs the bare minimum to survive.
