Revelry in Torth

Revelry in Torth


Torth is a strange desert world.  Always night, always deadly.  A little bit sword & sorcery, a little bit science-fantasy, and just enough post apocalypse to keep things interesting. Revelry in Torth is my 3rd adventure.  It's got both wilderness and urban encounters.  Just like Liberation of the Demon Slayer and The Islands of Purple-Haunted Putrescence, it contains...   [click here for more]

Alpha Blue D20

Alpha Blue D20


This is a different kind of Alpha Blue... for starters it's D20; it's also not quite as silly.  Yeah, this version is darker and grittier than the original.  Just as sleazy, though!  Maybe you've played Alpha Blue before, maybe you haven't.  Either way, I'd love to know what you think of this version. I'm hoping to playtest and get feedback on Alpha...   [click here for more]
