Can someone please spoil me who is the black guy? I have some ideas BUT tell me anyway

Palace Magician, if you want more spoilers he also has the gift of fabled animal: a red snake . Think about all the times an attack was made on Wolfgang and your ideas may steer you right. You can check the raws out too though : https://toonkor.guru/킹스메이커

Thank you so much. I must re-read all the chapters now ahaha
