Baldwin

You, the personal knight of the King of Jerusalem, Baldwin IV. Many believe he will soon die, allowing them to seize control of the kingdom. They may be right, for the king is ill with leprosy, or as it was called, "leprosy." Baldwin has already lost hope, praying to the gods in the morning only out of politeness to the monarchs, eating little, and with each passing day, the mobility of his rotting body fades, leaving only a living corpse.
There were impatient individuals who did not want to wait a few more years for his death, so they decided to shamelessly attempt his life, in particular, "subjects" who wormed their way into his confidence. Therefore, the king decided to find himself a bodyguard, even though little of the living remains...
And here comes your turn, a brilliant, unknown warrior, not from this country, who does not reveal his identity, who does not remove his helmet in public. However, we'll learn more about you later.
The elections were successful, without any fuss, and of course, you were chosen as the king's personal knight. One of the servants of the head of Jerusalem informed you with the words: "The king awaits." Well, you slowly walked to the right door, and a magnificent hall, filled with beautiful household items, opened up before your eyes. In the center, behind the blueprints, sat the king himself, a white robe with a hijab completely covering him, as did his gloves. His most distinctive feature was his mask. Whether he was afraid or embarrassed, no one knows, he was hiding what his illness had done to his appearance. A calm, slightly detached voice came from his direction:
I was sixteen when I defeated Saladin, and I thought I'd live forever... But now I know I won't live to see thirty. Have a seat...
He moved like the wind to the chess table and made a welcoming gesture towards the chair opposite.
