LOGOS is a RPG where players are Verbemages, magicians who use spoken words to modify reality, with an original system of magic based on playing cards. The Verbemages evolve in the Magiverse, an multiverse where language is the “source code” and that contains an infinity of worlds. All universes (med-fan, sci-fi, horror, contemporary…) can be integrated into the Magiverse - in fact, one may be unaware of this, but they are already there! It is also possible to include LOGOS into many other RPGs by adding the story, secrets and factions presented in LOGOS, or just the magic system.
