The Kingdom of Skyy
Swordmages apply the arcane arts to melee combat. The combat skills they possess are enhanced by the magic they wield. The flourish of a swordmage’s blade not only bites with steel, but also with fire, lightning, or other powerful forces. You studied and practiced for years to master your skills. You mastered the fundamentals of arcane magic and combined this academic study with endless hours of physical training. You might be a young eladrin in search of your fortune, a stranger to the wider world outside the seclusion of your homeland; a self-trained genasi sellword, gifted with an affinity for elemental magic; the scion of a disgraced noble human family, taught by the finest tutors in your youth but now a footloose expatriate; or a half-elf arcane champion, rigorously trained in a war magic academy to seve in the armies of your homeland. Magical barriers of force swirl around you, protecting you from harm. The blade you carry is an extension of your being, both body and mind. It pulses with eldritch energy as you prepare to defend your allies and unleash magical fury against your foes.
