The Magician Who Rose From Failure

Cursed with a naturally low supply of aether, Arcus Raytheft is disinherited and shunned by his family. Things start to change when he experiences another man's life through a dream—a dream that shows him marvelous technological wonders that don't exist in his world. Armed with this new knowledge, Arcus sets about showing his parents that they were wrong about him. Surely an arsenal of mind-blowing spells will be enough to convince them you don't need aether to succeed? (Source: J-Novel Club)
