If you have enough tiny robots you can assemble things using microblocks of preassembled atoms such that you have precise control over the complex atomic structure, leading to materials like carbon nanotubes at the most basic end and complex metamaterials like her bones at the more advanced. The same technology also allows for extremely rapid assembly because of scale effects - many millions of machines working in parallel at a very small scale where the distances needed to move things are almost zero.
They have no intention of majorly flouting local law, though they will of course lobby for their services to be made available to as many people as possible.
Trains are common in many other worlds of similar technology level to this one. Highly advanced "bullet trains" persist for some time into the future as one of the better long-distance travel technologies.
The OTC is generally noninterventionist in the greater sense. Clearly there will be some disruption as they connect to the multiversal economy, but so long as they aren't secretly condoning slavery somewhere the OTC will have no intent to majorly intervene.
There are worlds where the gods are real and tangible things; there are also worlds where they are mostly comforting hopes against an uncaring universe. Some gods are kind and just; others are right bastards. They're not much different from people with power. If she believes in anything, she believes in herself, and in the magic she's cultivated from her own soul. That's her opinion on gods.
You have to be able to dedicate the pain to takkarash-making, so a certain degree of intent is necessary. It's possible to dedicate the pain of getting a new tattoo, less so to dedicate a chronic pain you've been having for years. You have to be meaningfully making a sacrifice, choosing pain you could have avoided.
She's aware of many druidic traditions regarding the spirits of animals, but see her answer regarding gods; she's not certain any given way is best. So she respects them, in a kind of vague, general way - she does her best to use all of what she kills if she's forced to hunt - but she doesn't follow any specific tradition.Taking the opportunity to ask that question on a public stage shows Druidic potential, though; she has a friend that the reader might like to meet if she's interested in hiring on with the OTC.
