Well in a story where necromancy is really central, I feel like true resurrection spells would be really rare. And also Raise Dead is a 5th level spell. I don't think it would be common even if resurrection spells were common in the setting.

While they are rare, they aren't so rare as to be beyond the reach of wealthy, well-connected nobility like the Everhearts. I think I have an idea on how to keep this story making sense though, so don't worry too much about it. I just wanted to make sure you didn't have any explanations in place before I implemented my own.

Also, I wouldn't like teleportation magic to be very avaialble, feel like this would crash with the trains. (And I hate it in Critical Role when they just teleport to palces lol, I love the journey).

Trains would still have their place even with teleportation. Many such spells can only send so many things. And low-end teleportation spells can even be harmful. So you needn't worry about Professor Finch's Arcane Locomotives becoming obsolete when you're thinking about how to get around.
