One step backwards and to two steps forwards. You must lose to gain more. You must sacrifice to prosper. The Sludge, while adamant to stay alive, does not crave its own growth, and lives to serve and teach mortals. While it eats memories, it does not consume anything that the mind derives from them. Its followers eventually become great empty-minded sages - masters of logic and quick thought, and ridiculously fast learners. It teaches determination, persistence - the joy of learning and the power of knowledge - the difference between the smart and the wise.
