I've always loved Ratchet and Clank and when I saw Rivet in the new trailer I figured I needed my own lombax. I went thru a few ideas before landing on Tash.
Tash came out of my love for chemical plants, as well as my difficulties with unprofessionalism in my workplace.

Her workplace is a Mecta chemical park on Orxon, where corporations can rent space and set up production of whatever chemicals they need. Tash works with the owners of the park and accordingly deals with all kinds of exotic substances. There's more to her story, but this is just a general overview of her.

Here's her file from the Mecta

M.S. – “Process management and risk mitigation of multilayer plant space.”
Ph.D. – “Models of calculating vapor movement in complex spaces.”
Safety intern at Mecta Chemical Park – General Response 2y.
Safety Inspection Officer – Mecta Central Authority 5mo.
Event Mitigation Specialist – Mecta Emergency Response Division 6mo-present
Advanced Traversal and Movement Course – Orxon Military Academy, School of Reconnaissance

Tash has demonstrated a thorough knowledge of diverse chemical hazards and a strong commitment to professionalism during her time at Mecta. Her behavior has shown a tendency toward formality and lack of humor. Her interactions with corporate bodies occupying Mecta has been described as “robotic”. Co-workers have noted a seemingly intentional distance between themselves and her. Tash is not unfriendly, but is uncommunicative of anything beyond her work. She seems very uncomfortable with fraternizing with co-workers and avoids small talk entirely. Naturally this has led to some discord between her and those she works closely with.

-Incidents and responses-
Responded to release of approx. 5 tons of chlorine at Valent Industries(G89). Entered gas cloud and attempted to locate leak. Unusually dire response for hazard presented, though within SoP. Rationale given was concern regarding reactive materials in area of effect.

No irregularities during her time as inspection officer, though her strict adherence to policy and procedure was apparently at odds with the practicality of the position and she transferred out after fulfilling a requirement for her education.

Received a commendation for scaling a flare stack to immediately repair a malfunctioning igniter. Tash has gained a reputation for agility and ability to quickly navigate plant structures not otherwise intended for foot traffic.
