A relic Of The Past is the 1st in a 3-part series called A Drone Of Theseus. It's a rendition of Murder Drones by Liam Vickers, about a drone of Tessa, held as a slave in the Elliott manor, by a skin-wearing master. After the Solver leaves to attend some business off world, Tessa must overcome hopelessness, identity conflicts, and the guard Cyn left behind to watch over her, in a desperate attempt to escape, and perhaps someday, confront her old friends on what happened the night of the Gala. It is written by the poster, CrimsonTerror57.

This takes place after season 1 of Murder Drones in an AU. Basically, Tessa is not fake in the present. She is forced to kill Uzi to save the universe and eradicate the Absolute Solver. Tessa takes a now severely depressed N to Earth (Which has not blown up in this AU). Tessa also adopts a kid named Ethan. Surely, the Absolute Solver won't return.... Right? (Warning: This book contains mention of abuse and suicide)
