Silver Sword of the Astral Plane is a legendary, highly enchanted (+3) special variant of the Greatswords family of weapons. It is a martial melee weapon that's wielded with both hands.
The fervour with which the githyanki express devotion to their queen is admirable to some, disquieting to others. When confronted with the fallibility of the divine (since no one is wholly perfect), who knows what reactions such folk might evince.
