Game of Thrones: Savage Emperor!

Crouching Tiger, Hidden Dragon in the Middle Ages. Is it normal for me to recruit a few soldiers for my own safety? There is still black magic in this world, which is very dangerous. For safety, it is reasonable for me to establish an iron cavalry, right? There are a lot of psychopaths here. Is it normal for me to wear armor and make some exaggerated decorations to scare them? By the way, are there any other White Walkers here? Is it reasonable for me to form a war group to fight against evil? So, this is your version of Game of Thrones as Ride and Blade? Ahem, I'm actually playing a farming game. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
