He was solitary in the cabin, with the only other presence being the inorganic Kuat-Entralla piloting system. From the Retreat's small spaceport, he headed directly for the garden beyond the memorial. In a grassy clearing surrounded by hedge and stone reliefs, Knight Ashina reveled in the breeze and morning sun for several drawn-out moments of serenity.0700 Hours Local Planetary Time

The blade sliced the vacant air time after time. A dancelike routine began in step with a phantasmal rhythm. Deliberate targetless strikes made the plasma purr with every inch.

Soon.
