Lucille

Personality:

Lucille, on the surface, has a child-like demeanor that makes her the party's daughter. She generally tries to see everything in a positive light -- and near everything, it seems -- seeming mostly unfazed by the dangers and horrors that seem to lurk around the city she's grown up in. Though she trusts in her other teammates to get the job done, Lucille herself tends to deviate from the others to lie in wait, often swooping in to help in a pinch, only to then wander off to return to her idle plans. 

Last of note is Lucille's fascination with the occult. In particular, she believes in a forgotten god that only she and one other see to be true, referring to the god as nothing other than 'her'. Because 'her' cannot be seen, much like a ghost, Lucille sees ghosts as 'servants of her' or even 'parts of her', and has a generally positive outlook on ghosts despite their reputation.  

Background:

Lucille grew up to a family of rich inventors, who praised her intelligence and craft at a very young age. Though very smart, Lucille was also very naive -- and because of this, many of her inventions were written with patents under her parent's name, rather than her own. Eventually, her work becomes so well known that it costs the lives of her parents -- and suddenly, with a stranger after her head, and a home no longer safe, Lucille ends up on the streets.

Eventually, Lucille finds herself among the Dockhands -- a group of thieves all seeking belonging -- and easily becomes close to them. Her craft gets put to use through making concoctions and other strange formulas to influence their enemies, while her general charm and innocence keeps her from being seen as a threat to their adversaries. 

By the time their group had become to make a name for itself, their most recent member, a ghost, turned on them in order to fulfill their purpose of avenging their murderer. When Lucille and the others realized this, however, they decided to work with the ghost in order to give them the revenge they most definitely deserved, and, once done, watched the ghost move onto the afterlife.
