Fiddlesticks - The Harbinger of Doom

Fiddlesticks

There are many rumors of Fiddlesticks' origins. Some say that he is the avenging guardian of the witches of the Howling Marsh. Others believe that he is some sort of abomination gone wrong; a product of the mad scientists of Zaun. Barroom stories say that he is the creation of Noxus, a thing of evil which not even they could contain. There are even those that whisper that he comes from the forbidden Shadow Isles, but such learned men often keep to themselves. Whatever the truth, Fiddlesticks has come to the League of Legends, a malefic champion whose mere presence is a warning - something wicked this way comes.

A living scarecrow, Fiddlesticks is a magical creature born of fear. His simple presence is enough to cause panic in his enemies - when gripped so, they can scarcely land a blow. Drawing on the dark magic that animates him, Fiddlesticks can suck the life out of those who oppose him, adding to his own. When he fixes his sickly green gaze upon foes, he can cause terror so profound that they flee screaming. Proving that he is what he appears to be, Fiddlesticks can mystically unleash a flock of bloodthirsty crows which fly out onto the field of battle to pluck out the eyes of any who stand before them. As if all this weren't enough, he can both harm and silence his enemies when calling upon a cruel, autumn wind.

Ezreal - The Prodigal Explorer

Ezreal

Ezreal was born with the gift of magic flowing through his veins. However, Ezreal was also born with a much stronger sense of wanderlust. Though enrolled in Piltover's most acclaimed school for skilled young techmaturgists, Ezreal quickly became bored with magical studies. By the time the boy genius was eight years old, he had fully mapped out the underground tunnels of Piltover. The quality of his work was so remarkable that the government of Piltover purchased his maps and commissioned his services as the city-state's Master Pathfinder. This sealed the deal for Ezreal's true calling - he would eschew the arcane arts in favor of archaeology. Since then, countless adventures of his have been romanticized and published.

One of Ezreal's more recent adventures brought him face-to-face with his other legacy - his latent magical power. While exploring the pyramids of the Shurima Desert, Ezreal uncovered an amulet of inestimable power. He barely managed to extract it from its sandy abode due to its sheer magnitude (it was made for a being easily twice Ezreal's size). After fervent investigation, he found that it allowed the wielder to control and shape magical energy - provided there was a source of magic nearby. This permitted Ezreal to tap into his latent magical abilities without having to put any serious effort into it - a "big win", as the young prodigy notes. The lingering drawback is that, for some unknown reason, the amulet is highly attuned to summoning magic. This means that without warning, Ezreal may find himself acting as a champion for, as he puts it, "a summoner hell-bent on resolving some irrelevant world-shattering League conflict." Still, Ezreal feels that being summoned to a Field of Justice on occasion is a small price to pay for his prized artifact.

Dr. Mundo - The Madman of Zaun

Dr. Mundo

It is said that the man now known as Dr. Mundo was born in the city of Zaun without any sort of conscience. Instead, he had an unquenchable desire to inflict pain through experimentation. By the time he was five, most of the pets in the neighborhood had gone missing. By his teenage years, his parents were nowhere to be found. By the time he had legally acquired his license to practice medicine, he had been acquitted of 38 charges of murder by the Zaun authorities; the lack of evidence made prosecution impossible. Unfortunately, the city-state of Noxus regards such behavior as a sign of initiative and ambition, rather than inhumanity. Dr. Mundo was recruited to fight for Noxus in the League of Legends. He continues his experiments to this day, even using himself as an experimental subject.

Zilean - The Chronokeeper

Zilean

In the wastelands of Urtistan, there was once a great city-state. It perished long ago in a terrible Rune War, like most of the lands below the Great Barrier. However, one man survived. He was a man obsessed with time, a sorcerer who dwelled in the giant Clock Tower of Urtistan named Zilean. As the Rune War devastated his homeland, he experimented with powerful temporal magic that he hoped would bring peace. Instead of perishing with the rest of his kind, Zilean survived and was afflicted with chrono-displasia. This mystical disease made him immortal, but also made him detached in time. His consciousness now drifts through time, from any point he has already lived to the present. Zilean's greatest curse is that he sometimes experiences Urtistan as it once was and the rest of the time resides in its lonely ruins. The Chronokeeper has joined the League of Legends hoping to either find a cure for himself or a way to bring his people back from the past.

Anivia - The Cryophoenix

Anivia

In most lore, the phoenix is a creature of fire that rises from its own ashes. What few know, however, is that phoenixes are elemental beings, formed by the eternal essences of their native world. Anivia was conceived on a world such as this – a being of the coldest winter, a creature of pure elemental ice. On her world, Anivia was the protector of the frozen wastes and all those with the spirit to endure in such unforgiving places. She was consulted as a creature of great wisdom, one who could not die and who had seen the world renewed several times. Somehow, Anivia knew that the day would come when she would be plucked from her home and pulled across worlds, and when that day came, she received the call with grace. Seeing the imbalance and injustice on Runeterra, a world lacking elemental protectors, Anivia took residence at the League of Legends.
Anivia is an immortal being of intense power. She can instantly freeze a path in front of her, covering all in its wake with thick frost – she can even force the cold to violently explode, throwing razor sharp ice shards in every direction. She can also concentrate this ability on a single enemy, riddling his flesh with deep frostbite. The cryophoenix can also summon a glacial storm, a blizzard of terrible fury that both harms and slows those within. When defense is needed, Anivia can create an impassible barrier of ice. Furthermore, Anivia can never die. Whenever she is killed, she simply transforms into an egg, waiting to be reborn.
