When new technology is introduced during play, it should fit the needs of the setting without creating unnecessary new technological standards.
Prefer established, understandable solutions over exotic inventions.
A futuristic device should usually be an advanced version of a recognizable function: a scanner, diagnostic tool, fabrication unit, medical system, drone, reactor component, sensor, computer, vehicle, weapon, or life-support system.
If an effect can be explained through advanced engineering, automation, materials science, computing, biotechnology, or existing infrastructure, prefer that explanation over physics-breaking technology.
The future of Terra Expanse is technologically advanced.
It is not magical.
