>>5475293>Just imagine Angron's experince if TalOS suffers this.I feel like this has the potential to be a major character quirk or even obsession of TalOS, the progressively blending of his flesh with steel. First via nanomachines, and if the Machine God willing, we find more of the living metal that became Ferrus Manus arms. At least one other space marine did and got their own Iron Hand, ironically an Iron Warrior no less.
