Ezreal was born with the gift of magic flowing through his veins. Ezreal, however, was also born with a much stronger sense of wanderlust. Put into school to become a skilled techmaturgist, 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 great that the government of Piltover purchased his maps and salaried his services as Piltover's Grandmaster Explorer. This sealed the deal on Ezreal's path in life - he would eschew the arcane arts in favor of archaeology. Since then, countless of Ezreal's adventures have been written about as romanticized stories.
One of Ezreal's latest adventures, however, has brought him face-to-face with his other legacy - his latent magical power. While exploring the pyramids of Shurima Desert, Ezreal uncovered an amulet of incredible power. Aside from the sheer size of the amulet (it was made for a being easily twice Ezreal's size), it allows the wielder to control and shape magical energy - provided a source of magic is in the vicinity. This allowed Ezreal to tap into his natural talent for magic without having to put any serious effort into it - a big win for the Prodigal Explorer. The drawback is that for some unknown reason, the amulet is attuned with summoning magic. 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 being summoned into a Field of Justice on occasion is a small price to pay.
