Instruments that were always going to exist.
We just got there first.
Discovered, not designed.
The best instruments never feel invented. Nobody has ever needed a manual for a spoon. You pick it up and your hand already knows what to do, because the shape was settled long before anyone thought to patent it. That is the standard we hold ourselves to. If a thing needs explaining, we are not finished.
So we try not to think of ourselves as inventors. Nature has been designing sensing instruments for a few billion years, eyes and ears and the prickle on the back of your neck, and it has firm opinions about what works. We study those opinions, follow them as far as they go, and build the thing they seem to have been describing all along. Then we get out of the way. If it looks as though we discovered our instruments rather than designed them, that is because, mostly, we did.
Four, so far.
Each one stays under its cloth until it is ready to be met. When you do meet it, you will not need an introduction.
Vigilo
I keep watch.
It keeps watch in the places nobody is looking. It knows the difference between something happening and nothing happening, and it only speaks when the difference matters.
Sentio
I sense.
It notices the things a room would tell you if rooms could talk: warmth arriving, air changing, the slow drift of a day going wrong. It has no opinions, only a very long memory.
Vestigo
I trace.
It remembers where a thing has been, which turns out to be most of knowing where it is. It goes along quietly and leaves a trail only it can read.
Custodio
I guard.
It holds what it is given and gives it back only to the right hands. It cannot be talked into anything, but it can be asked nicely.
We keep quiet on purpose, not by temperament.
If you have a reason to talk to us, write. Someone will write back.
