Est Machina is a work by the troper Morgulion. It chronicles, from first person POV, the travails of the nanomechanical construct GANT 01, who joins, through sheer chance, a venerable mercenary company consisting of two people: (Isako Itou and Ben Holz). Later joined or opposed by Jacob Renstein, Alexander Karr, Maria Dage, and Nicholas Gerem, he finds that the once-decaying world is slightly different from what he considered. If you want to read it, PM Morgulion and he'll mail you a copy. Critique is always welcome.
