Hello, community. First post. Love the game and love the setting.
I was thinking of creating a new exoplanet that has recently been discovered and is similar in its environment to Echo IV (or could just be Echo IV if I'm lazy). The twist being that some of the explorers have disappeared due to being discovered by primitive alien culture that attacked and ate them. The concept of this species was inspired by this artwork: http://img.gawkerassets.com/img/18dycrwt0l3nhjpg/ku-xlarge.jpg
The aliens use a hunting technique similar to the mimic octopus where they use their malleable bodies and chromatophores to take on a wide variety of forms that are utilized to infiltrate prey groups, pick out a target and paralyze it with a neurotoxin analogous to jellyfish toxin or to hide from predators. While the aliens can pass for human at a distance or in low light conditions, the limits of their impersonation are apparent to anyone paying attention. However, the imitations were enough to lure small exploration teams that were not expecting to see a human into ambushes with other mimics disguised as plants.
Being that this is my first homebrewed creation in Eclipse Phase, I'd like to how appropriate this would be to the setting of the game and to know possible ways that this concept can become expanded into a campaign.
