When it comes to Wrench, most people are met with her sarcastic tone and 'just let me do it' tone. This seems to rub badly on people and on first impressions, seem to start her off on the wrong foot. This is all due to her unable to trust many people and just assuming everyone is out for themselves, so if she doesn't make any relations with people, there is a less of a chance of being heartbroken when they betray people, or upset they are leaving. Wrench also has a
tough skin and not many people are able to get under her skin or really piss her off, but are easily able to annoy her. The only times she has legitimately gotten mad at someone while on the Lullaby was when a new hire installed a pair of hyper disaminator's upside down, and when the old chef insulted her dead parents.

But if people are able to get through her shell, either by being able to handle her sarcastic insults and return them or even leaving 'tips' and presents after she is done working, they will see Wrench doesn't only have sharp edges, but can be a bit soft with people. Those that someone earned her trust, will have someone who will ride or die to the end, and even when outmatched, someone to stand in their corner and stand up for them. Her priorities are her job first, her few friends second, and herself third. She can be seen hyper focusing sometimes on a task, which often takes up too much of her time and leads to her being found pass out along benches or leaned up against a tool cabinet.

While her trust is hard for anyone to earn, her trustworthiness of machines, ai's and even implants is not there whatsoever. Only trusting things she has created herself if she has to trust any sort of walking and talking machine. Working under the AI Captain of the ship took Wrench some times, but she eventually moved those issues to the back of her mind as working on the Lullaby was her last chance and just made it work.

Wrench's life before being a grease monkey was one she cherishes, but also pushes to the back of her mind as she wants to focus on the future rather than living in the past. She was born in the city of New Haven on the forgotten colony planet of Daveterra III, her mother was a scribe and her father the local maintenance worker, in charge of keeping the factory running that kept the planet sufficient, as well as whatever other mechanical issues the residents would have. Her mother obviously wanted her daughter to follow in her footsteps with the archives and record keeping, but Hene’Giscaos was fascinated by her fathers work. What started with just holding a flashlight and being tasked to get whatever tool her father requested, to learning all her father's tricks and becoming his apprentice. But her parents were just happy that their daughter enjoyed herself. She would even hang out at the local port and watch the mechanics there and eventually become the local grease monkey for them, learning all she knows today.

All was going well for the Sari family, until her father bought a droid off a traveling salesman, one that would assist him and his family at home while they were busy at work. But only a short few days after having the robot, something in the robot's wiring malfunctioned and while it was supposed to be cooking them family, it went haywire and ended up killing her father, trapping her mother in the upstairs, and causing their dwelling to burn to the ground with her inside. Fortunately, or in her Hene'Giscaos' eyes, unfortunately, she was working on a ship that had an emergency landing at the port. Since that day, she hasn't trusted another bot, and always making it known.

With no home, and now a debt to paid for damages in the city, Hene'Giscaos left her planet as a stowaway on a ship and began just traveling and working wherever she could. Unfortuneatly, she was found as a stowaway and sold into slavery. Though once her mechanical talents were discovered, she was quickly bought out of her servitude and 'hired' to work aboard a traveling maintenance ship. Hired being a loose word as she wasn't allowed to leave and forced into work hours, but still paid a small amount for her work. Her name being a bit too complicated for the common man, she was quickly given the nickname Wrench, due to always having a wrench attached to her belt loop, her father's. Wrench spent years upon this maintenance ship, honing her craft and often being put on the hardest jobs. But she was getting tired of this life and wanted to be free, so she decided to run again the second time in her life. Though like all other times in her life, it didn't work out as planned.

Wrench was caught and disciplined, before being branded a Refugisast, basically an outcast who betrayed someone who took them in, and tossed out at the next space port. The brand being forced in the center of her chest marking her forever. She would take on odd jobs here and there to survive, all until she was caught salvaging parts from an Alliance ship graveyard. She was then given the choice of imprisonment for stealing government property, or working for them. Wrench saw this as an opportunity, and negotiated to work on star ships due to her skillset, though she wasn't expecting to be put on a ship as the Lullaby.
