Author has written 6 stories for Warhammer, NCIS: Los Angeles, A song of Ice and Fire, and Chicago PD.
The guy in the picture is Honda Tadakatsu aka "The warrior who surpasses death itself". He rose to be a senior general for Tokugawa Iyeasu in the later part of the Sengoku Jidai, a period of instability in Japan that began with the collapse of central authority around 1467 and ended with the formation of the Tokugawa shogunate in 1603. It makes the Wars of the Roses look like a school ground play fight.
I am nowhere near being a percent of a percent of the badass that Honda was. I am a fan of the trope Reality Ensues, as well as A Song of Ice and Fire, the NCIS franchise, Person of Interest, Skyrim, Assassin's Creed, Bourbon whiskey, cigars and rare steak. From time to time I write stories about these things, which I hope people enjoy.
