Tsuba of the Lotus
Wondrous item, legendary (requires attunement)
You can attach this tsuba to a longsword, greatsword, rapier, shortsword, or scimitar by pressing the tsuba against it for at least 1 minute, at which point it replaces the sword’s hand guard.

Ciroji kneeled on a jumble of blankets, sharpening her blade next to the lake. The stars danced below in shallow ripples, shining their light into her sightless eyes.

Without hesitation, she attached the tsuba to her katana and felt its magic mingle with her spirit. Slowly, with each breath, an ember of light began to grow, expanding ever brighter. A tapestry of color emerged from this light, and took the shape of a moonlit lake surrounded by towering pines.
For the first time since she was a young child, the blinding sickness left her body. Ciroji gazed upon a world that had hidden its beauty from her for too long, and readied her blade for the path she could now see before her.
