Nice idea.
I don't think, he would craft anything for Lara. Except if it would be less expensive and more practical to make the rings by himself. So if he would make a ring for Lara, it would just be for tracking.
She is pretty capable of protecting herself. No need for extra powers.

For any other loved one he would make a ring he could track (he could do that anyway with any object he crafts himself, especially a wedding ring, as it is supposed to be connected to his own wedding ring) and I'd say for communication with another wizard or a force ring for a vanilla mortal.
If it is possible to do both, he would go for force and communication for vanilla mortals.

Doing anything like force or shielding would be ridiculous with another wizard or the Winter Lady IMHO, because they could do that themselves and some even better.

So for wizards he might also do a sort of amulett, to let them behind the wards of the castle.

So tracking is included anyway.

Vanilla: force and key to the castle
Wizard: communication and key to the castle
Vampire: just tracking

Though if you could do three things with the ring, I would put in communication for the vanilla, too, if it is possible to use without magic.

Edit @ Mira:
For protection from some person/monster, I don't think, it would be practical to craft something the other would wear. It would make more sense to craft something for himself i.e. any person he wants protected.

I only used flashlights a few times. There was the escape problem mentioned by Fcrate, and it wasn't really good light, and my parents asked about all the missing batteries. And there was the danger of falling asleep and being caught in the morning with a flashlight in your bed.
And it was too hot and bad air under the blanket.

Oh no, Dina, I hope it gets better tomorrow.
I'm still at home until the end of the week. Today and yesterday I read an old children's book to my little one. I did not remember it to be written in such a funny way. Or maybe I didn't understand the humour as a child.

My parents also were not fond of my closed door. I did it only so that no one would see the light, but argued that I did it, because I couldn't sleep, when my father was snoring so noisily? LOL. And that was no lie either.

@Dina: I'm quite sure I'd have been too lazy to follow through on anything.

LOL
Me too, I'm afraid. I was the kind who hid fantasy books in school books to pretend I was learning. To imagine what I would have done, if no teacher watched me... 

Good maen.
I just woke up and looked outside.
... Mab decided to stay. She left snow everywhere!!! Enough to build a snowman. 

Boris the pirate?

Arjan, what did you do??? There is snow here, too now! 

Again, if Justine hasn't survived, will Thomas want to live?  Then there is the child, is it even his?

What I've been asking myself: Can we be sure there even is a child? Is she really pregnant or was that a lie?
Does the real Justine even exist any more and if not, when exactly did she cease existing? If she is still there, does she truly love Thomas or is Nemesis just faking the love burns somehow?
I'm not really convinced, the pregnancy is real.

Maybe it's just me, but isn't there a blindingly obvious solution to Thomas' condition that Harry is in a unique position to be aware of?
Harry knows about the situation between Irwin Pounder and his white court fiancée Connie. Irwin survived the first encounter when Connie's hunger awoke, which previously was inevitably fatal to the victim, and continues to be fed upon without ill effect.
So why doesn't Harry call in River Shoulders and his kin to see if one or more of them can feed enough energy to Thomas to stabilize him without endangering anyone's life? The Forest People can handle the drain without serious risk, even with Thomas' hunger in the negative feedback loop it seems to be stuck in.

I thought that, too. But as stated by others before: how to ask? Who should do it? Danger of being exposed as endless food supply to other WCVs.
Is it even possible to still the Hunger anymore in any way?

I can totally see future WCVs hunting down Forest People (Bigfeet? ) to imprison them as food supply.

But maybe in the future, when Thomas will be on Demonreach for several years, Harry will tell River about it. Just telling him about the situation, not implying anything. And River Shoulders would offer on his own to take care of Thomas, if it even can be done.

But personally I think, Harry will find a way to separate the Hunger from his brother, leaving him human, probably even with some magic, an arc of redemption and a potential wielder of Amoraccius.


Edit: And [Battle Ground Spoiler!!!!!!]

Just to make sure it is justified to stay inside. I did that too. Minus the rain and the arctis.
