Red Mage
Xander Boyce
When the Advent kills every electronic device on Earth, Drew Michalik survives a government bunker-turned-dungeon by slotting Xatherite crystals through a mysterious mana interface — becoming a spellcasting Red Mage. Across three books he and his team conquer system nodes, found a Habitat for humanity's remnants, and hold the line against Naga and Sidhe forces while human factions fracture around them.
Progression: System-apocalypse LitRPG progression: the Advent disables all electronics and grants survivors a mana interface with blue-screen prompts. Power advances by slotting reality-altering Xatherite crystals to gain and improve spellcasting (Drew becomes a rare Red Mage), clearing dungeon zones, and conquering nodes to found system-recognized Habitats; later volumes add faction-level advancement and alien Naga/Sidhe threats gated behind node control.
