Atsaan wasn't exactly a dark God to start off, though. He was formerly an ancient in his own fragment of their domain. Once he went crazy, the other ancients sealed him away for good. He had little to no interest in Ludus itself, however, except that it was the location where he just so happened to be sealed. Apparently. You could make the argument that he could have gotten in touch with the book, but again, he had no interest in such objects. The book could not break his seal, and I don't care how strong you say it is. Thusly, it was just another unnecessary value in his plans.
