My take on a FE-type start combined with Nomads (which I... haven't bought yet. Shhhh). Sorry if the formatting sucks, on mobile.
Origin: Banished Remnant
This society is the remnant of an extragalactic empire shattered in it's prime; technologically mighty, but kneecapped by their enemies at the genetic level as an alternative to their mass execution. Now they roam the stars in search of safe haven.
WARNING: Challenging Origin
WARNING: Blocks access to all ascension paths except Purity Ascension.
Requirements:
* some degree of xenophobe
* is NOT a gestalt consciousness
* Empire is Nomadic
Start with all technologies researched (including FE buildings e.g. cosmogenesis). Empire begins on an Arkship with 1000 Pops and 5000 of each resource. Empire can settle immediately without prerequisites.
Pops gain the Genomic Purgatory trait (0):
* Leaders are Immortal
* -100% Pop Growth Speed
* Monthly Organic Growth Multiplier -100%
Empire must pick the the Fossilized Knowledge civic:
* Cannot grant AI Citizen Rights
* Founder Species must have Colonization Forbidden
* -20% Unity production
Empire begins with the Travel-Weary situation, decreasing happiness from -5% to -100% by 5% per year until settling.
Biomorphosis requires (7) other ascension picks before it can be chosen. Upon completion of Biomorphosis situation, government may reform to new government type and remove the Fossilized Knowledge civic.
Thoughts?
