Christmas gifts
Harding - A tiny AM/FM radio, made to look as if it had come from the 50's, but fixed with a futuristic power source that will easily keep the thing running for YEARS.
Darren Nichols - An embroidered handkerchief -- the letters "O. W." -- and a note explaining that it did actually belong to Oscar Wilde; Miniver had stolen it with his own hands (and Robbie Ross's approval). Call it a good luck charm from a theatre master.
Draco and Mia - For the two of them, Miniver has Bar help put together a basket of various candies, biscuits, and assorted dried goods and canned soups from his time -- including Jello, and some cheeses and pepperoni -- with written descriptions of what everything is and how to prepare all of it if one tended to use magic and not, say, refrigerators. Or stoves. Essentially, it's a "cooking for wizards who can't actually cook" kit.
Ginny - A few fashion magazines of the type found in hair salons, with a note telling her to look through these to find the sort of style she wanted, and tell him when she wants it done.
Guppy - A number of tiny bottles of potions Miniver's made -- and tested -- himself; no larger than perfume tester vials, there are twenty that encourage peaceful sleep, and twenty that give a significant energy/focus boost, both non-addictive and without side-effects.
Jack Frost - Five bottles of ice wine, all quite different in color and sweetness.
Moon - Several pairs of glittery, colorful, or otherwise funky earrings, and toys for Mons and Mare and the puppies.
Robbie - A handsome, leatherbound calendar, its pages numbered and labelled in gold ink, the paper thick enough to prevent any ink from bleeding through, the front cover stamped in gold with Robbie's current year.
Roger Ratcliffe - A pad of blank music paper for composing tunes, and a book of sheet music for Irish folk tunes. Also for Pongo, a chewtoy shaped like a martini glass. Har har.
Ravin - A silver Victorian locket with highly detailed engraving, inside a tiny rosebud encased in glass.
Sam Linnfer - A pair of warm leather gloves, a fancy flask with a leather grip, and a bottle of good-quality Irish whiskey.
Tom Riddle & Family - A basket similar to Draco and Mia's, with wizarding instructions included in addition to the muggle ones, plus a book about origami for Ingress.
Will Scarlett - A simple but attractive double-edged dagger with a black ceramic blade -- it's almost as hard as diamond, amazingly light, and will stay sharp ten times as long as a steel blade.
YT - A messenger bag -- the kind that has pockets for EVERYTHING, and is made from materials practically intended to survive a nuclear holocaust, should its owner happen to ever stroll through one.
