Offworlder

Off-worlder is a term used for any human that comes from a different timeline or universe. Thankfully, this term is not considered derogatory.

The Vanguard's leaders often peruse parallel universes, planets, and timelines and come back with technology and people. This ranges from aliens, and even humans from any point in time. Considering the world is well aware of this, these new travellers usually have to specify that "they're not from around here". Therefore, this term was created to make it easier for them to specify that they're not as familiar with the surroundings.
