"I originate from Earth. My region is stabilized by the false belief held by most humans on Earth that magic mostly does not exist. Because of this, I advise acting with discretion on Earth. I mostly live in a demiplane."
"Like Golarion, our region is threatened by entities which I suspect would locally be called Dark Tapestry entities. Interacting with them is bad and they should be avoided or killed on sight. We don't have a Pharasma and incursions aren't rare. I personally have defense obligations, and am obligated to pass on these warnings under some circumstances."
"Onto nicer things: We have different magic, and also nonmagical technology you don't have. People on Earth don't travel by horse, much. Moderately wealthy humans tend to have carriages powered by petroleum derivatives or stored lightning. Less expensive than that are two-wheeled vehicles, powered by the rider, which are more energy-efficient than walking on a smooth enough road. A lot of people have small machines that run on stored lightning with a range of capabilities – emitting some light and sound, sending messages to other humans with the machines, storing representations of books and songs, performing calculations, sometimes recording images of their surroundings. I have one which I brought, but I altered it to not function without my personal magic, so I can't demonstrate it to you at this time. We've automated the spinning and weaving of cloth. I have access to instructions for many of these things and can telekinetically manipulate metal to produce the ones which are made of metal. There's a lot of other things in this genre."
"I don't know what your highest value exports will be. I do suspect that truth magic would be popular. The best we can manage is faerie contracts. A lot of people don't want to sign faerie contracts and most witches and faeries with the capability to produce them don't want to work as notaries."
