On the idea of travelling contients, what if there was something like a World Roots system or an Arcane Web that espeically talented/qualified individuals could take as means of instant transport? Could expand it that people have managed to make "rail cars" to transport others ot just have people be able to use them but have to pay for it like an airplane ticket to use the gate or something. Could also have people attempting to make their own gates or accidently coming across one in the wild if htey were made a long timeago.
