Magic greatly impacts the world of Numira, but it isn't as widespread as one would expect. Few can wield arcane powers, yet many more can understand and fight against it.
Spellcasters in Numira are called "Markbearers" or the "Marked". To begin channeling magic, one must inscribe a Spellmark into their flesh. It is a bloody ritual, but it's a sacrifice that many choose to make.
World Codex
Magic has shaped every part of Numira. Even the mightiest army can easily be defeated by a few powerful Markbearers. Arcana, however, requires the souls of the dead as fuel.
