Frontline Champion: Neville, A Master Chemist

Lore: As a successful alchemist under the Magistrate, Neville was often told tales from his old masters as to how the Magistrate was slowly turning possessive even before the golden age; the crystal discovery was a catalyst to their desire for power. He was at first reluctant to join the Resistance for fear of his reputuation. However, his contrbutions to, the unanimously inhumane, project Terminus was the last straw tolerating the Magistrate's misdeeds. The Battle at Crosswind Hold came and went but after some time, he was ready.
Currently, he is a part of the Resistance but this time, the Magistrate's hypocrisy shall be their downfall by his hands.
