Giliath Osborne also known as the Blood and Iron Chancellor (鉄血宰相てっけつさいしょう) is introduced as the Erebonia's chancellor and leader of the Ironbloods. Giliath Osborne was the representative of Erebonia's government that was entrusted complete control from the emperor and therefore controlled all of Erebonia's domestic politics, international negotiations and military affairs until his death in S.1206. His declaration that 'Our nation's peace must be built on a foundation of blood and iron' earned him the nickname of Blood and Iron Chancellor. He excelled at grasping his opponents' weaknesses through information warfare and progress talks with favourable conditions through negotiations and behind‐the‐scenes manoeuvring. From his time as a civilian employee of the imperial army onward he showed great talents, leading to high expectations from those surrounding him.
