Daneel had really been taking it easy, as he knew that even if the Aegis team failed horribly in keeping them safe, he could just use the aura of the Godbeast to scare away the Great Sharks.
True, the last time he had used this idea, it had almost ended in a disaster with Skrr, but this time, the situation was under control.
These Great Sharks were just oversized beasts which had used the abundant Energy present in the Endless Sea to grow to a size where very few things could even hope to harm them. They might be the descendants of a Godbeast, but that didn't mean that they had the same power, or prestige.
Hence, when faced by one which used to terrorize even their ancestor, they would have no option but to flee, or die.
