Crimson and gold
Ring of fire
- "But then, through the darkness, fire erupted: crimson and gold, a ring of fire that surrounded the rock so that the Inferi holding Harry so tightly stumbled and faltered; they did not dare pass through the flames to get to the water. They dropped Harry; he hit the ground, slipped on the rock, and fell, grazing his arms, but scrambled back up, raising his wand and staring around. Dumbledore was on his feet again, pale as any of the surrounding Inferi, but taller than any too, the fire dancing in his eyes; his wand was raised like a torch and from its tip emanated the flames, like a vast lasso, encircling them all with warmth."
The firestorm is a charm that produces a ring of fire around the caster. When the caster moves, so the ring of flame will move with them in the same direction, swirling like a flaming lasso. The caster can also shoot jets or balls of flame at individual targets or opponents, which inflict a small amount of damage to them. The spell Partis Temporus will temporarily create a gap in the flames to allow safe passage through.
In June of 1997, Professor Albus Dumbledore and his student Harry Potter entered a seaside cave in an attempt to locate on of Lord Voldemort's horcruxes. When the Inferi guarding the horcrux attacked them, Dumbledore used this spell to drive them back into the water and protect Harry and himself until they reached their boat, therefore saving Harry's life.
Behind the scenes
- In the book, the spell merely conjured a lasso of flames, like a rope made of fire. In the films, however, this was dramatised to have a wall of flame swirling around them, filling up most of the cave, with Dumbledore shooting fireballs at the Inferi underwater.
