Animated Portrait Set
One set of fully animated portraits.
They twitch, and blink, and look around, and breathe, just like vanilla portraits.
The set comes with male and female variations, facial variations, headgear variations, cybernetic Ascension, psionic Ascension, Biogenetic Mutation Ascension, and a clothing set.
The base portrait is available for selection in the Reptilian class.
The synthetic variant is available for selection in the Machine class.

City Set
One custom city set to go with the portraits.

Empire
The portraits come with a custom empire (Ancient Technosethi), a custom name list (Serpentoid), a custom solar system (Kheshem System), and a custom building (Astral Pyramid). If you create a custom empire using these portraits from scratch, it will NOT have this flavor, but if you create a custom empire by modifying the Glorious Crescent, it should retain the flavor.
Astral Pyramids work as a mixture between Slave Processing Facility and Temple, although you can only build one for each ruler (when your Pharaoh dies, you can build another one for his successor, etc.).


The portraits come with a pre-created empire (which can spawn), but they are set to NOT be used randomly by the AI.


Pretty much everything. No vanilla files have been altered.


If you use the base set and go through a full synthetic evolution, the portraits will have a more limited diversity of looks (as compared to taking the machine portrait from the start). This couldn't be fixed without going into editing some vanilla files, which would have severely reduced compatibility.
Note that going full synthetic will default portraits to the vanilla class initially. Once you have completed the Ascension's situation, you'll be able to create a template of the species with the appropriate portrait.
