Aetherological Crystalpunk RPG

MEGALOS is a game for telling stories about adventures in the clouds, fighting evil empires, and dueling ancient gods. The Worlds of MEGALOS are vast and old, each a cosmic emanation connected to one another by the Wellspring- the source of all aether in the cosmos. Make your own World of MEGALOS or play in one of ours, from the Oradam Rift to Pallid Telkane to Zone Gachette to The Erefane. Soar through the air in an airship, dogfight imperials, and wield aetheric magicks as a punk-rock witch.

This tabletop game is inspired by things like classic JRPGs, electronica music, and medieval alchemy. MEGALOS is the first of my games to use the SLIPSTREAM game engine, which uses pools of d20s as the core of its task resolution mechanic.

Crystalpunk Fantasy. Challenging Tactical Combat. Built for Adventure. Welcome to MEGALOS.

MEGALOS serves a platform to support multiple different settings and genres in a layered multiverse built onto a shared framework of aetherological science.

The MEGALOS Core book features all the rules you need to play in any World of MEGALOS, or to create your own. It comes packaged with the first MEGALOS Worldbook, The Oradam Rift, a world of floating islands drifting amidst the vasty emptiness of a chasm cleft from north to south pole in a planet called Gaaln. The Oradam Rift is a place of magick and magitek, of imperial crusades and desperate revolutions. Adventure awaits, from the Unshrouded Lands below to the Ebon Moon above.

The game was successfully funded with almost 140% of its original goal. The game has been in development for almost 6 years at this point, going through a dozen iterations and total system redesigns. But finally, it has becoming a reality.

Current Version: v1.1

The game is NO LONGER in Early Access & is fully released!

• A new edition, v1.1 has just been released as of July 2023. This edition corrects some things, clarifies others, and adds in a bit of errata. Please see the v1.1 Announcement Post for more information or see the downloadable errata sheet.
