"Okay, so, it is unknown exactly when it was invented, but it's thought to be around 500 AD," he said as he was in front of the class once more to explain it better. "The first records of it are in ancient Persian libraries, but they are not the inventors. The tribe that invented it doesn't have a name or origin in the records, but Persians provide us with a logical and satisfying story.

"The potion is used by the tribe in the holy rituels to honour the dragons, because they were their gods. As I've already said, it has salamander blood in it that is an ingredient used to cure, but the tribe didn't know it then. They thought it was the holy dragon spirit that cured them, and the recipe was their most prized possession. Just imagine, the dragons are even more impossible to tame in those days, and a potion that enables them to breathe fire like them cures them, warms them up on cold winter days and because it is fire, scares off other animals. It is still a handy potion out in the wild, and for us modern people, the most important property is the 'curing'. It is easy to brew and you will recover from flu in less than a day. It is also good for scars and light illnesses like flu.

"As for what happens if you drink it, I saw some enthusiastic students among you to demonstrate." His eyes SHONE. "Why don't we give them a chance after we are done with brewing?"

He smirked again and tapped his wand at the board for the ingredients to appear.

• 3 goose feathers (chopped WELL that they look like powder)
• 5 centimetre square of parasites (mycosis fungus)
• Roughly 2 centimetre square fire-crab shell (prepared)
• One fire slug
• 8 drops of salamander blood
• Some flobberworm mucus (depends on how much rigidity one wants)

"The feathers and fire-crab shells are already prepared and are on my desk, where you can also get a culture of fungus." Mycosis fungus. Should he warn them, in case they didn't know what it was? During brewing, maybe. "The size of the shell depends on how much you want to brew. We don't want to spend all Hogwarts money, so we are keeping them small." He EYED them. No playing around with them, okay?

"Only the fire-crab shell part is modernised. They used to use a plant for that, but it is extinct now due to the wars that destroyed its habitat." He sighed dramatically. "But the effect is the same, so let's start brewing.

"Fill your cauldron 1/3 with water, please, and do not light a fire undernearth.
