64) Start a citystate-kingdom of kobold archmages.
That is what it had to be after favoring the kobolds, and their utterly mindboggling rate of reproduction... and that that rate of wizards (sorcerers?) towers springing up... a dozen or so a round. And later a hundred, if someone could be bothered with the accounting.
Eventualy incomes were in the 12000 BP range, and accounting simply stopped.
Supposedly the world would be covered in wizards towers in a few more decades at that rate of growth. Im kinda assuming they began masscrafing demiplanes for those kobold wizard towers :p
Oh and the kingdom had absolutely no farmland at all.
Magic items, thats where business really is.
Armies consisted of a few archmage legions, many more apprentice legions, and golems. Yes, whole armies golems. That just retarded development for less than a single kingdom round per golem army. Scary? Yup..
