Fire Magic was a type of magic involving the generation and manipulation of fire. Capable of great destructive power, fire spells were often used to cause widespread damage or kill opponents.
Fire magic allowed the user to conjure flames of varying sizes out of nothing and manipulate them to an extent. The flames could reach heat strong enough to incinerate human beings or entire towns. In battle, casters could launch their flames at opponents, use their concussive force to knock back opponents, or generate a blinding light with them. It was also possible to form the fire into different shapes, such as a snake.
The sorceress Irina Clockworker and the Demon of Greed were both known for having powerful blue flames; Irina in particular could minutely control what the flames burned, allowing her to avoid burning the target's surroundings, or specific body parts of her target themselves. Due to its unique nature, fire magic was immune to normal water and could not be doused by rain; in contrast, the flames could be put out by water magic.
