Now like all other non-magical mundane humans Jasper and Marina were aware of the general politics of the Magical Continent that was separated from the mundane world in order to keep the magic over there from bleeding and being depleted by the mundane world.
A billion users of magic over there,technology and weaponry over there about
70 years behind where the mundanes were.
Basically World War Two
prop driven fighters and bombers,submarines,Sherman tanks and battleships rather then nuclear submarines,missiles and drones
such as the mundane armies used.
Not as modern tech as the mundanes but never the less nothing to sneer at.
With their use of magics on their technology the Magic Users were a force to keep mundanes hopping on their toes.
What Jasper and Marina didn't know was that the Old Man was a Agent for one of the more hostile warlike nations on the Magical Continent
a nation heavily into transformg humans
both magic and mundane
into
Monsters-of-War
