JD coming, yay! I'll have to move the computers off the table, move the laundry basket on the table, and move the table, but that's where we can put a sleeping place. Will be good!
Tired. Way tired.
I can explain Death Note without spoiling too much of either the series or the manga. "Wacky hijinks ensue," is how I phrase everything after the notebook and the guy who picks it up and the conclusion he comes to and the reaction of the Powers That Be to same conclusion.
Note on Mary Sues: Do not give them the only piece of anachronistic tech. Especially do not give them the only piece of *that* anachronistic tech. If they are supposed to be background characters, do not use them to explain what this cool piece of tech is. Give it to someone else first, have it explained on someone else, and then they can be seen -- in the background -- with their version of it.
This is apropos of Myste, Herald-Chronicler. So far as I know, Myste is the only person on the planet who wears spectacles, because they were made for her by a Blue. CAN WE SAY NO. The way to introduce spectacles and make it OK for Myste to wear them without comment would have been to have an aging Herald with failing eyesight, and the Blue would have come up with the device, and then Myste and all the rest of people would have been able to see straight.
And of course that was spurred by M's world, where there's a lot of worldbuilding going on. M makes the fantasy happen, and then she checks her science against us, to make sure that it holds to at least a soft-handwaving level. We also do continuity and stuff.
