The Hallows was a cylindrical chamber half a mile across, plain white in colour. Around the walls, about five feet from the ground, ran a ledge. Standing on this ledge, shoulder to shoulder, were tall, magnificent figures, twenty feet high, robed and winged in white, mighty swords rested point-down between their hands in front of them. Solars; the highest angels of the Gods of Good, placed here by each of the deities of Alair to watch the Sword of Law - for ever.
The Solars paid the pair no visible attention, but the sensation of being watched was overpowering. With it, though, came immense peace.
