Recalling A Vision / Terra Incognita

In a towering realm where moonlight cascades,
A knight awaits, in silver parades.
Across uncharted lands, his vessel glides,
Dreams reverberate as fate abides.

On a strong steed with thunderous might,
Waves in the sky that dance in the moon's soft light.
A vision bestowed, a prophetic scene,
Of a lone knight, stalwart and serene.

"I heard your call in a dream's mystic breath,
Like a frail flower facing autumn's gentle death.
Guard your garden, oh keeper of the night,
Deserve not the blight, nor the pain in its might."
