He is on a - hill? No, not a hill. He can see the curvature of the horizon, that's not just where the ground drops away.

There is a field of lavender here, and a woman picking the lavender.

He takes a deep breath, assembles his requirements in his head, and then demands of reality that it explain its physical characteristics in his immediate vicinity. 

It is, as it appeared to be, a field of lavender. He is standing between two rows of it and the lavender continues in all directions in the inspected radius; the woman, who hasn't noticed him yet, is outside of it. The dirt is well-watered, good quality soil and remarkably free of stones. The air is breathable, and the wind is light, and the sun is shining warmly. There is a snail over there.

And the weirdness with the curvature of the horizon?

It's just actually how this planet is curved.

It's about nine miles in diameter.

...Okay. He looks around for a sun, or any other visible celestial object.

Yup, there's a sun over there.

There's another one, smaller or farther away, over thataway.

And a very small or very faraway one, still too large to just be a pinprick of a star, over there.

Also there are - moons? Lots of moons, way more of those than suns. With stuff on them.

He reaches out to the "moons."

They are like what he is standing on. Some of them are a bit smaller; the one he's on seems to be one of the larger ones. Some of them have more people and some have fewer.

He considers the woman picking lavender, checking with his eyes to see if she's visibly noticed him and with his magic to see if she's any amount of mage. 

She's not a mage at all. She hasn't noti- ah, now she's standing up and stretching and notices him! "Something in a foreign language!" she says.

What did she just say? 

She said "Oh! Hello! Where did you come from?"

He makes a helpless shrug. 

"I certainly didn't make you!"

He nods. He gestures off into the distance, then at his feet, then makes a puzzled face. 

"...can you talk?"

He shakes his head, then coughs dramatically. 

"And you don't know where you came from?"

He makes a so-so gesture. 

She squints around in the field. "Hello?!" she calls. "Who made this man? Look, it's still illegal, but it's a lot less illegal if you fess up and explain what you did!"

No one answers.

...Who made this man? That's...an interesting question to ask. Is there anyone besides the two of them on this little planet moon thing?

Yes, but not nearby; in a handful of villages there are concentrations of people and in between there are groups not exceeding three.

Are any of these people mages, or at least hedgewitches?

Nope!
