The Sword of the Unknown Hero

This artifact has a will of its own and appears from time to time. Some claim it to be a bastard sword, but there is no hard evidence of this. According to tradition it can be found seemingly at random, turning its discoverer into a mighty warrior. Armed with the Sword, the warrior may avert disaster or perform some other great feat, but he will never be recognized for his effort. He may die before anyone knows he made a difference, or perhaps no one will believe him. Whatever the reason, he will never get credit for what he has done.
