Elthos RPG Gamemasters Tools help you to Create your own Worlds.

Introducing the Mythos Machine

The Elthos RPG Mythos Machine is a wonder of 21st century technology that fuses your web browser with the Elthos RPG Rules System. It is a fully integrated Game Prep tool that helps Gamemasters create and maintain your own Worlds by smoothly and efficiently doing all of the number crunching for you, and providing a centralized online location to store your World’s Characters, Places, Adventures, and History. It comes with a number of auto-Generation features which can be wonderful time savers for GMs.  It also allows your players to generate and maintain their Characters online. The Mythos Machine is a comprehensive system designed to make your Gamemastering faster, easier and more elegant. It also encourages and builds on the idea of a Mutual Collaboration Society of Gamemasters where GMs can freely share their creative work with each other through the Web Interface.  By creating a unified underlying rules system for all the Worlds in the system it makes sharing things such as weapons, armors, classes, races, and even characters between Worlds easy. Premium Gamesmasters can even create Shared Worlds, and offer their own Packaged Worlds for sale at a price they set to other GMs on the system via our Worlds Market Place!  It’s a must have GM Prep Utility that focuses on Simplicity, Flexibility and Creativity as its Primary Directive.  Check it out!  You’ll be glad you did!
