Harry Potter is the much loved book series, (and later turned into movies) by JK Rowling.
The Tale of the Three Brothers is an important tale in the Wizarding World, it tells the story of the Deathly Hallows, Three magical objects that when brought together are said to evade even Death himself, to become "The Master of Death".
"Three brothers, travelling along a lonely, winding road at twilight reached a deep treacherous river where anyone who attempted to swim or wade would drown. Learned in the magical arts, the brothers conjured a bridge with their wands and proceed to cross.
Halfway though the bridge, a hooded figure stood before them. The figure was the enraged spirit of Death, cheated of his due. Death cunningly pretended to congratulate them and proceeds to award them with gifts of their own choosing.
The eldest brother, a combative man, asked for a wand more powerful than any in existence. Death granted his wish by fashioning the Elder Wand from a branch of a nearby elder tree standing on the banks of the river.
The three brothers took their prizes and soon went on their separate ways.
The eldest brother travelled to a village where a wizard whom he had quarrelled lived. He sought out a duel and fought the wizard using the wand, instantly killing the latter. Leaving his enemy dead upon the floor, the eldest brother walked to an inn not far from the duelling site and spent the night there. Taken by his conscience and lust of the Elder Wand's power, the eldest brother boasted of this wand gifted by Death and his own invincibility. That very night, Death transfigured to a murderous wizard. The unknown murderous wizard crept to the inn as the eldest brother slept, drunk from wine. The wizard slit the oldest brother’s throat for good measure and stole the wand. That was when Death took the first brother.
The Elder Wand eventually passed down into the hands of the Headmaster of Hogwarts, Dumbledore, who wanted to use the wand for the good of the Wizarding World. The wand finally ended up in the hands of its final master, Harry Potter.
There are a great many number of spells in the Wizarding World, some able to cast light, shoot out great beams of fire or water, allow the user to teleport a great distance by thinking of a location, unlock bolted doors, bring objects hurtling towards you, wipe the memory of someone, make an objects size double in size, and much much much more! Wizards are forbidden however to use the three "Unforgivable Curses" the torturing curse, the mind control curse, and worst of all the killing curse.
