Spirit made flesh, or something deep like that
One of my magical experiences involved a potter from Tumblr whom I would not discover until many years later.
Years ago, I worked at a commercial ceramics studio. At this time I was painting and firing many little magical tools - bowls, figurines, and so on.
I wanted an empty vessel to build a servitor (artificial spirit) inside of. I got ahold of a discount figurine and glazed it, whispering it's purpose to it.
Now I was not building the artificial spirit. I was building an empty vessel. A container which was designed to hold a spirit, right. I was actually very sure at that time that the firing process was magically galvanizing, a process of awakening not unlike rebirth from a grave, and so would make a great medium for creation of such things.
I fired the piece and when I pick it up, it's immediately evident to me that something is inside of it. I hadn't created or called a spirit, but one was within.
It initially took on the appearance of the figurine itself (which was a Christmas elf). It spent a few minutes trying to convince me that I was an amazing wizard who spontaneously generated spirits by intent alone, but even back then that wasn't my first rodeo. I demanded it show it's true self.
Its appearance rapidly changed into something I had never seen before. It was like a bipedal wolf-person, but it wasn't a wolf or a person. It's most distinctive feature was it's wolfish head with long, triangular ears that protruded from the skull. It's eyes were slits, and it was a long and lanky creature.
After it revealed itself to me I asked it to leave. It did so, traveling north. I never saw it or anything like it again.
Until several years later I stumbled on @claypigeonpottery's portfolio of their kiln gods.
I just about had a heart attack!
There it was, the same creature. I hadn't thought about that old experience in years and years, but the kiln god was so identical in nature to what I had seen that the entire experience flooded back to me.
I usually try to conclude these things with some kind of pithy wisdom but I haven't got one, except that gods are everywhere and most of them are quite a bit smaller than you'd think.
