Ah yes, of course. Well, not quite. You see, the Takmahl failure and collapse was quite preventable. They just made the wrong mistakes in interpreting the Apocryphon.
You see, the core principle of Sani Sabik as opposed to Amarr Orthodoxy, is that one can transcend ones origins far more readily. Amarr Orthodoxy generally has slaves, commoners, and nobles, with very little mobility between them. Sani sabik holds that if one is strong enough, even a slave could rise to the very top.
But, and this is where the Takmahl went wrong, this requires a social & economic system where such social mobility is possible. Free education for all, as an example. So that those with potential, regardless of their origins, can be identified and make the most of their talents.
