Rising World

Tom wished for a meaningful job with the chance to make things. Someone listened. Judged by a masked demigod, Tom gets sent to another world with magic, game-like rules, and massive opportunity for a clever inventor. He's been handed a new identity and adopted by a loving family. As a young man with otherworldly knowledge, he tries to recreate technology from humble beginnings. There are spells to learn, too, and he wants to treat his sister and parents right. His river homeland seems idyllic, but there are problems brewing.

Vonn the Engineer has invented the airplane in a magical world, using his secret knowledge from Earth. He's just crash-landed next to a living, unholy dungeon with a prisoner to save. And when he returns, there's real work to do. So far, Vonn has used the arcane rules of the "System" to earn spells and other powers. There's no dark overlord to slay, so he and his friends are free to build. This kingdom's technology is just starting to take off, partly thanks to airships and tools powered by the physics of magic crystals.
