Meet the father of my main character, Bothvar Beorcolsson in my book Broken Souls, Beorcol Thorgrimsson. He’s the Earl of Stormfront Village and the Kraken Clan. The reason that his skin color is grey in the two pictures is because they discovered a glowing green metal ore growing in the mountains to the north that has glowing green mushroom growing around it and they discovered if they drink water saturated with the metal it increases the potential strength and speed gained through training and hard work so they can become far stronger than any average human. In fact, you have to drink the water and strengthen your muscles through rigorous training just to be strong enough to even be able to pick the metal up. Eating the mushrooms enhances your senses and increases your ability to heal, healing the worst wounds overnight with some sleep. Combining the two vastly increases strength and speed gained from training due to the fact that the mushrooms increase the rate at that muscles recuperate and heal after the tears they endure from strength training.
