"Do they have mental properties like Silmarils or could I just make myself an inertia thing?"

"They shouldn't be a problem to duplicate at all."

"Are there multiple design options or are they all the same? What do they look like?"

He pulls his collar loose and pulls off a necklace. It is exquisitely pretty. "The only necessary bit's this here in the center," he says, "if you want it harder to remove from you than a necklace or something."

"How valuable would it be stolen?"

"The Enemy has as many as he wants - well, no, that's probably not true, but he has enough one is not a marginal advantage. In Valinor one could easily amass thousands."

"I'll just wear it then - are there any others I should accumulate, put 'em all on one string?"

"You could pull up the list of what I have, this one has a couple hundred on it. There's one for vastly improved recall and working memory that I find particularly useful, but I don't think it comes in non-chip variants."

"Now that's tempting as all get out," sighs Cam.

"One of my brothers is working on a chip that doesn't transmit anything. It'd mean no osanwe, which is half the fun, and only local backups, which is dangerous, but might serve your purposes."

"Might take it," Cam agrees. "I can define things that are sufficiently attached to me as part of my body and count them in the indestructibility but I don't know how that'll do against read-only attacks." He produces a list of blessings.

Balance (chip), reflexes (chip), autonomic control (chip), deflecting projectiles (area-effect), grounding electricity (touch), wireless charger (area-effect), eloquence (chip), working memory (chip), recall (chip), temperature (area-effect), better osanwe range and precision (chip), sense magnetism (area-effect), improved visual acuity  (chip and surgery), improved auditory acuity (chip and surgery), ability to see ultraviolet and infrared light (chip and surgery), temporary strength (area-effect), temporary inertia (area-effect), healing (touch)...

It's on his computer so he can grep it by whether he can actually use it or not. He totally wants most of the area effect ones though.

"We can also develop new ones for you, it's a two-month development process even if you're really in a hurry for people who aren't the King or Curufinwe but it can be done."

"What kinda stuff wouldn't have to go on a chip?"

"Things in the vein of what's already out there - I know breathing underwater's in the development stage now that we all live underwater, but I assume you can just make yourself air - withstanding water pressure's also in the development stage - flight, which again you already have, is perpetually being attempted - the temperature blessings all have safeties on them which stop you from changing your vicinity to Elf-unsafe temperatures, we could make ones without the safeties if you wanted the ability to make the area around you absolute zero -"

"Hm, not obvious must-haves... Anything that'd make me better able to track the locations of things I wasn't looking at would probably be the chiploading kind..."

"There are some sensory ones that aren't chip-loading, if they hijack existing senses - like magnetism you sense in your fingertips, sort of, though once you get used to it it just feels like having an intuition that something is magnetic. I bet something like that could be done for spatial awareness."

"That'd be cool, I have decent accuracy hitting stuff I can't see but it's not perfect."

"I'll tell a team to start developing it. We should probably at some point have sat down and gone over all our capabilities and the ways they might be useful to you but I have a lot of people under my command and it'd be a very long sit down."

"Yeah, I'd imagine. Do you need any more of these trinkets conjured up for your people?"

"Everyone has them. We could do them for the locals."

"Lemme know when you've assessed demand."

"There'll be demand, it's constrained by concern about whether this is escalation."

"Yeah. I'm hoping there's a line between stuff you couldn't do and stuff that'd take you a while."
