This Sarmizegetusa has 21 luxury palaces, 76 grand insulae, and 41 medium insulae, for a total of 13864 population.
The palace block is a bit of a mess since I added the forced walkers later, leaving gaps filled by oracles.
The savefile has been edited to remove the random clay pit events.
--Update--
Raised city health to average, cleaned up some fountain efficiency, fixed a couple pesky devolutions, and raised the culture rating. One library is needed to finish the mission (so long as caesar continues to get his damn giraffes).
