Give Darius the Persian sword for his father.

With one fluid motion, you draw the Persian sword from its sheath at your side. "Here you are, Darius," you say, kneeling in front of him in a slightly overdramatic gesture. "A sword fit to grace the wall - or the side - of a man like your father. Persian work, I'm told. Beautiful, but deadly. And most certainly exotic. A fine gift for a man of his tastes."

Darius leans forward, eyes alight. "This is...perfect! Thank you, Gaius." He hefts the sword and gives it a few gentle swings. "What strange weight. But it's exactly the sort of thing my father goes nuts over. Excellent, excellent work! I'm sure he'll be thrilled. I can't thank you enough."
