Flame Sword Summon

The magician named Stiyl Magnus grabbed the cigarette from his mouth and flicked it
away to the side.
The lit cigarette flew horizontally, over the metal railing, and hit the wall of the
neighboring building.
An orange line traced the cigarette’s path as an afterimage and sparks flew when it hit
the wall.
“Kenaz (Flames).”
The instant Stiyl muttered that, the orange line exploded.
A sword of flames appeared in a straight line as if someone had turned on a fire hose
loaded with gasoline.
The paint gradually changed color like a picture being scorched by a lighter.
