In Greek mythology the gods could only contain Typhon for minimal time, just like Gaea. It took all the gods together to put him to sleep, and it was still hard to defeat him. In the end they could only contain his power for a short time. Gaea is the 2nd most powerful deity after Chaos itself, and Typhon is thought to be almost as powerful. Both Typhon and Gaea could only be contained until they would kill the gods. Kronos was defeated completely(surviving only because of his immortality) with only three of the gods. The book exaggerated the power of Kronos. Typhon could destroy him in a matter of seconds. Gaea says herself said Typhon is her most powerful creation ever, and when he was “defeated” she left the gods alone, because there was nothing more powerful she could create. All things said are facts I have researched.
