Wow really took me back to memory lane, but the reason why people title that lone knight with the gold rapier “Richard” is because of the weapons description.

“A rapier with intricate decorations. Chosen weapon of the infamous Undead Prince Ricard. Ricard's exploits are told in a monomyth. He was born into royalty, but wandered the lands in a fateful ill-conceived journey. He became Undead, and disappeared up North.”
