Amethyst Compendium (4E)
A 4E-compatible roleplaying setting presents Earth divided between advancing science and encroaching fantasy. Players choose science- or magic-based characters and explore regions where ruined cities and factories are overrun by elves, goblins, and dragons, while contending with monsters, machines, and rival factions. The rules include ten races, technology-focused classes, traits, paragon paths, epic destinies, modern and futuristic equipment, powered armor, customizable vehicles, monsters, setting material, artwork, and a world map.
