The youngest member of the Wrench warband, Sidera - known as "Sid" by her bandmates - was found as an infant progeny in the destroyed remains of a merchant caravan that had been set on by Separatists. As the asuran merchant had been a friend of theirs, and the aging warband was well aware he had no love lost for the home he and his family had been banished from, they made the decision to take in the girl and raise her themselves.
As such, Sid isn't a very good asura, but she's a very good (if quite small) charr, despite her appearance. Having done her own time in the fahrar with the scars to prove it, she learned to hold her own from a very young age, using a quickly developing bright intellect and her small size, needle-like teeth, and sharp claws to her advantage.
After her time there, at the behest of Galen Wrenchtoss, she was given back to the Wrench warband's care. She grew up climbing in and around charr war machines and weapons, and her sharp mind fixated on improving their output, making the devices made by Wrench some of the finest the Iron Legion had to offer, despite the advanced age of many of its members.
Sid is known to be crass, loud, and surprisingly sturdy when drinking with bandmates, but she's deeply loyal to her warband and the Iron Legion at the end of the day. She's known for her startling sense of humor, razor sharp wit, and deep affection for the warband that's been her family since as long as she can remember.
She and Iuno Wrathtalon (@wall-legion) have been best friends since they were young in the fahrar alongside Calix Quickwrench's youngest cub Pirithous Forgemind. Though they all went their separate ways, Sid and Iuno have since managed to reconnect.
