I guess I will update again.

This is a short, necessary addition, telling what the Sword does...
The Priest slammed the box down on the table. For a man of such a slight build, he was stronger than he looked. Samuel watched him examine the oblong silver box. Johannes nodded. "Yes, it does say the sword of Muhammad the Prophet. Let me see if I can open it..." He looked around for a lock. "Ah, here. Popular Arabic locking mechanism. Give me some time to crack it."
Samuel grabbed a bottle of whiskey and sat down.
Later...
Pop.The box opened. Inside was a medium-sized, double-edged, sword, very ancient. It had strange carvings up and down the blade, the like of which Samuel could not understand.
The Priest examined both the sword and text closely. "Greek. It's Greek. Looks like the Cyprus variety, just off the Ottoman mainland. I'm a little rusty, but let me see if I can figure it out." He stared at it for about five minutes and then rubbed his hands together. "I think I've got it. Let's see... 'Whosoever inserts this in it's slot in the Temple of Hercules will have power over the minds of men. Ask, and they will obey, go, and they shall follow...
write, and they shall believe.' This is what gave Muhammad so many followers! Wait! What's this on the hilt?" He carefully examined the letters on the very bottom of the sword's hilt.
" 'Alexander.' "Samuel dropped his bottle of whiskey, which made a loud shattering noise.
"What?""Yes,
Alexander the Great. The Alexander the Great."
"So Muhammad used Alexander's sword?"
The Priest looked at it in amazement. "Yes, the very same. If the Turks find out you own this, they will kill you without hesitation."
Samuel cringed. "What! This is horrible! Absolutely horrible! What should I do?"
The Priest shrugged and put on his hat. "Your call. I'd advise taking it to Cyprus and looking for this Temple of Hercules. I don't believe in pagan nonsense, but this sounds... almost believable. The main thing is to keep this thing out of the Turks' filthy hands. If the infidels use this... Well, let's just say prepare to get yourself a prayer rug."
Samuel gulped.
