"The God Shackle is a relic discovered by Anrakyr in the depths of the Star Hallows that allows him more exacting control of the C'tan shards in his possession. On Asphodex this would even allow the Overlord and his Crypteks to boost the power of the Burning One, rather than relying on its innate rage alone. The only drawback of using such a device is that the tighter the leash placed around a C'tan's neck, the more likely the creature is to rebel against it."
