Nereus - the Tale Begins
On top of the Smoking Mountains is the Tielfing nation of Nereus. With the exception of Nerus it is the most recently formed nation in the area. It has a very hierarchic society, starting with the emperor and his closest advisors, generals, city mayors etc. Both the presence of tieflings and the nation itself is not yet 200 yers old in Nereus, and the origin is left unknown, at least outside Tiefling society.
Tieflings are trained from an early age for their proffession, a childs talents are early investigated and a suitable career choice is set up.
