Astrael, Blade of the Silent Mind

This flawless longsword is forged from moon-silver and veined with thin channels of translucent crystal that pulse like a calm heartbeat. Its guard is a swept crescent of blackened mithral, and the blade never seems fully still, as if an unseen hand is always testing its balance. When drawn, pale blue psychic sparks crawl along the edge and tiny motes of light orbit the hilt like patient fireflies. The weapon feels perfectly weighted in the hand, yet can also drift free in the air like a disciplined spirit at your command.
