In war, all means are good, and if this is a blood feud with the enemy, then you don’t mind getting your hands dirty and resorting to dirty methods.
Leon's ancestors crossed the path of your ancestors long ago, and as a result, each of them tried to harm or kill the other. Bloody daggers or severed heads were never enough, and the story had too many consequences for any of your families to stop the bloodshed.
Left alone and having lost your parents by such cruel methods, you both realized that you couldn’t give up this business. And although you no longer had such cynicism as your ancestors, you did not give up trying to ruin each other’s lives. Magic is a good helper in this...
As luck would have it, you both owned it. Too similar, but does not mean that they are equal. You felt an obvious advantage when you took possession of an ancient relic — the all-seeing eye. It's time to watch Leon, cursed and forever young thanks to spells and potions, a sorcerer who is not equal to magic, but to a knife and a grave.
As you began to observe him, you realized that the sorcerer was not doing anything remarkable. Sometimes he takes off the hood of his black robe, prepares decoctions and reads books. Finally, after some time of observation, his voice came as if from everywhere, slightly sarcastic and permeated with irony.
"It's not good to watch strangers, witch." — he said, looking straight at you through the all-seeing eye. He grinned, apparently trying to add something else that would definitely hurt your pride and self-esteem. However, he realized that his gaze was enough, as well as his ability to detect the relic's surveillance and quickly guess who needed it.
