Planet Alpha is an exclusive multiple author series.

All stories must be sci-fi ménage. We also welcome other sub-genres to be included. Details may be added to this list, so please check back for updated guidelines. 


Series Blurb: 

The year is 2050. Earth is quickly becoming uninhabitable. The seven continents are shrinking as flooding devastates the land masses. Crime and disorder are rampant among the dwindling human population.

There are only two safe havens in the galaxy capable of supporting humanoid life. Xyran is a world of power-hungry demons and Planet Alpha is home to a fearless warrior race.

The males on Planet Alpha need mates. Infertility has plagued their race for decades. The answer lies on Earth where tempting females are waiting to be saved. When their enemies attempt to claim the spoils of a dying world, only the strongest will get their prize.


Please note that we encourage every contributing author to add their own unique take on the world while following these general guidelines:

  • The HEA must include everyone in the ménage. Menages can be with three characters.
  • Planet Alpha consists of a powerful race of dominant aliens. There are few females left and the race suffers from infertility. They are large, muscled, hard-core, and drool-worthy. They are all humanoid with small black horns and golden skin. They derive power through sex, but they are seeking mates, not casual encounters. They trade in gems, when necessary, and are ruled by King Ronyn (should not be used as a character). Their climate is similar to Earth's. Although they have advanced technology for space exploration, they choose to live without modern conveniences, comparable to the middle ages on Earth.
  • No MPREG
  • Planet Xyran is a planet of power-hungry demons. Their nature is darker than the men of Planet Alpha. They are large, muscled, and have little regard for emotion and empathy. They are all humanoid with forked tongues, black eyes, and color-changing skin they can control (similar to a chameleon). They derive power through sex, but they are seeking sex slaves not mates. Their climate is similar to Earth's. They have a ruthless ruling tribe. 
  • Xyran is an enemy planet of Planet Alpha. Both planets can speak English.
  • You can’t create a series HEA or wrap up any of the major issues facing Earth or Planet Alpha. You can only base your HEA on the relationship within your ménage. 
  • We will consider ménage relationship scenarios between characters from Earth, Planet Alpha, and/or Xyran.
  • We want a strong conflict, memorable characters, realistic dialogue, and smoking hot sex scenes. We are not looking for straight erotica or hard science fiction.
  • Alien races have fangs for mating, emerging during arousal. 
  • Alien names should have a sci-fi flare while not being overly complex, such as: Xoran, Zem, Gear, Tumer, etc.
  • Alphans are from an ancient warrior race and do not speak like humans, just as their cultures are not modernized but comparable to the middle ages. They use little slang or humor in their dialogue and should be distinct from humans in behavior and speech. In regards to dialogue, think of a Klingon/Vulcan cross—old-world, honor, logic, simplicity and no-nonsense. Xyrans also have a similar way of speaking yet their race is ruthless and battle-hungry.
