While ambling through the bazaar you over hear the end of a conversation.
"I'm sorry, ma'am. I'll put the word out, but I haven't seen a such a weapon. I'll keep my eyes open."
"Please do. Please let the merchant know I have a variety of excellently crafted weapons including other fine long blades, axes, daggers, gold, and vials."
A small notice can be seen in the window later that day: seeking a pale steel long sword(s).
