Atrusius is a world of science fantasy. When magic and technology are so blended together, where do the lines exist? When respect for natives is the primary concern of an alien colony, what conflicts arise?
Atrusius tends to focus on the natural within its scope -- the existence of planes and afterlives is only a minor aspect of this world, as are the direct interactions of gods, demons, and other cosmic supernatural forces.
Atrusius is designed for writing and roleplaying, and the RPG materials are planned to be available with system agnostic materials and system-specific materials for parts of the D&D family. Our current focus is on making the basic reference materials and modifications of those suitable for AD&D 2nd Edition and D&D 5th Edition, with a number of mechanical tweaks designed to flesh Atrusius out into its own distinct environment.
