RE: Recovery of High-Value Biological Material 

STATUS: Opportunity Active

The CySigma research vessel Nascence has ceased communications following preliminary confirmation of a diversification event within the trench systems of Pelagios I. Preliminary reports indicate the material exhibits non-hostilenon-sentient behavior. Manifestations: structural reorganization of organic matter, active interface with human neurology, emergent recombinant architecture.

KEY FINDING: Early data suggests extensive creative potential in living substrates, including human neurological tissue. Current applications under review (medical, defense, semiotic recursion technologies).

We advise urgency.

A recent survey of the ocean planet, Pelagios I, reported a potentially “high-value biological diversification event” occurring within the planet’s deepest trenches. The biotech corp, CySigma, quickly dispatched a vessel to investigate, hedging that this finding would have “strong upside for portfolio growth and cross-sector applications.” The vessel, The Nascence, went dark two weeks ago just after confirming its positive findings. CySigma are willing to pay a small fortune to recover what the missing crew found.

E I D O L O N S is a one-shot created for Mothership RPG 1E, dropping players into a well paying contract from CySigma, a bio-tech mega corp, to retrieve a specimen from their silent research vessel, The Nascence.  Once docked, they will see that the world inside the ship is more than what they were led to believe. 

This trifold pamphlet provides Wardens with:
✛ tables for encounters and observations make for quick prep
✛ a nerve-fraying underwater setting 
✛ a depth table that imposes the crushing realities of deep see travel
✛ easy to navigate ship map with node descriptions
✛ an option to play to a 3 hour clock to ratchet up real time decisions.
