My partner got me 40k: fire warrior right as a friend was planning a dark heresy one shot, so i ended up making a tau!
Behold: Shas'saal Ksi'm'yen Riaun
A cadet who ended up alone during a tyranid invasion, she ended up losing her classmates before fully ending up alone. Whilst gathering the bonding blades of the fallen squads she came across, Riaun ended up surviving off what ammo she could find, and when ammo wasn't enough, she put her blade to good use.
Eventually, a rogue trader comes along, scavenging for whatever valuables were left behind, only to find that curiously, the tyranids haven't progressed as far as they usually would have. It was then that one capiliary tower was blown up, and the tau that caused it was slinking back off into the shadows. The trader would find her, and the two would form a deal where he would take Riaun home though in return, she acts as a liaison of sorts.
That's how she ends up with the group!
