"Good man," Harry acknowledged. James fell into step next to his dad as they headed toward a staircase.

        "Wait!" Cadogan cried, sheathing his sword and jumping into the center of his frame. "Have I ever told you about the Battle of the Red Mages? Bloodiest massacre these walls have ever seen! Happened just at the foot of those stairs! Next time, then. Courage!"

        "Who's that?" James asked, looking back over his shoulder.

        "You'll get to know him," Neville said. "Enjoy your ignorance while you can."

        As they walked, James listened as his dad told Neville about the current happenings at the Ministry. There had been an arrest of several individuals involved in a counterfeit Portkey operation. More trolls were being seen in the foothills, and the Ministry was stepping up patrols to keep the troublesome idiots from venturing into Muggle territories. The new Minister, Loquatious Knapp, was preparing to give a speech on expanded trade with Asian wizarding communities, including lifting the ban on flying carpets and something called 'shades'.

        "In other words," Harry said, sighing, "things are more or less the way they always are. Little breakouts here and there, small conspiracies and squabbles. Politics and paperwork."

        "What you mean," Neville said, smiling crookedly, "is that peace can be a pretty boring thing for an Auror."

        Harry grinned. "I guess you're right. I should be thankful my job isn't any more interesting, shouldn't I? At least I get to spend most nights at home with Ginny, Lil, and Albus." He glanced down at James. "And take on an ambassador's assignment that just happens to afford me the chance to see my boy during his first week at Hogwarts."

        "I understand he's only been to McGonagall's office once so far," Neville commented mildly.

        "Oh?" Harry said, still eyeing James. "And what for?"

        Neville raised his eyebrows at James as if to say you have the floor.

        "I, er, broke a window."

        Harry's smile hardened a bit around the edges. "I look forward to the story of how that happened," he said thoughtfully. James felt his dad's stare like it was a set of tiny weights.

They reached a double doorway with both doors thrown wide open. Delicious smells wafted down the hall.

        "Here we are," Neville said, standing aside to allow Harry and James to enter first. "The Americans' quarters during their stay. We've given them most of the southwest turret. Had it temporarily refitted with a recreational area, common room, kitchen, and staff to suit their needs."

        "Sounds nice," Harry said, examining the space. The common room was, in fact, rather small, with circular walls, high, rough-beamed ceilings, a cramped stone fireplace, and only two very tall, narrow windows. The Americans had, however, been very busy. There were bearskin rugs on the floors and tall, vibrantly colored tapestries hung on the walls, positioned over the stone staircase that spiraled the room. A three-story bookcase was crammed with gigantic volumes, most accessible only via a very rickety-looking wheeled ladder. The most amazing detail, however, was a mind-bogglingly complex armature of brass gears, joints, and mirrored lenses that hung from the ceiling, filling the upper chamber of the room and moving very slowly. James stared up into it, delighted and amazed. It made a very faint squeaking and clicking as it moved.

        "You've discovered my Daylight Savings Device, my boy," Ben Franklyn said, coming from a large arched doorway beneath the spiral staircase. "One of my absolute necessities whenever I travel for long periods, despite the fact that it's a veritable bear to pack, and the calibrations when I set it up again are simply dreadful."

        "It's wonderful," Neville said, also staring up into the slowly ratcheting network of mirrors and wheels. "What does it do?"

        "Let me demonstrate," Franklyn said eagerly. "It works best in full daylight, of course, but even the stars and moon of a bright night can provide adequate light. An evening such as this should prove most satisfactory. Let me see…"

        He moved to a battered high-backed leather chair, settled himself into it carefully, and then consulted a chart on the wall. "Third of September, yes. Moon is in the fourth house, it is, let me see… approximately a quarter past seven. Jupiter is approaching the final leg of… mm-hmm…"

As Franklyn muttered, he produced his wand and began pointing it at bits of the Device. Gears began to spin as parts of the Device whirred to life. Bits of the armature unfolded as other bits pivoted, making room. Mirrors began to slide, positioning behind cycling groups of lenses, which magnified them. Ratchets clicked and shuttled. The entire device seemed to dance slowly within itself as Franklyn directed it with his wand, apparently making calculations in his head as he went. And as it moved, something began to form within it. Ghostly beams of rose-colored light began to appear between the mirrors, pencil thin, turning motes of dust into tiny specks of fire. There were dozens of the beams, brightening, swiveling into place, and eventually forming a complicated geometric tracery. And then, in the center of the tracery, shapes shimmered into place. James turned on the spot, watching raptly as tiny planets coalesced, formed out of colored light. They spun and orbited, tracing faint arcs behind them. Two larger shapes condensed in the very center, and James recognized them as the sun and the moon. The sun was a ball of rose light, its corona spreading several feet around it. The moon, smaller but more solid, was like a silver Quaffle, equally divided between its light and dark sides, turning slowly. The entire constellation weaved and turned majestically, dramatically lighting the brass Device and spilling delightful patterns of light over the entire room.

        "Nothing so healthy as natural light," Franklyn said. "Captured here, through the windows, and then condensed within a carefully calibrated network of mirrors and lenses, as you can see. The light is filtered with my own optical spellwork for clarity. The final result is, well, what you see here. Excellent for the eyesight, the blood, and one's health overall, obviously."

        "This is the secret to your longevity?" Harry asked, rather breathlessly.

        "Oh, certainly this is a small part of it," Franklyn said dismissively. "Mostly, I just prefer it to read by at night. Certainly, it's more fun than a torch." He caught James eye and winked.

        Professor Jackson appeared in the archway. James saw him glance from Franklyn to the light display overhead, a look of tired disdain on his face. "Dinner, I am told, is served. Shall we adjourn to the dining room or shall I have it brought in here?"
