"One of the Three fell ill. Deadly. Only I could save. Davel-Ka said I could not heal. His vision forbade it."
Writings of Medo-Ja[src]

Davel-Ka was a Voss Mystic living on Voss many years before the planet was discovered by the galactic society. He had a vision that prevented a great healer Medo-Ja from helping a dying member of the Three.
