According to the Insect Masters Alatak, Yue Lin, and Yue Liu, raising a single Gray Demon Whale to the Lord Limit would consume the resources of over twenty Lord Soul Beasts of the same Level.
The reason was simple. Although their intelligence was low, their bodies were robust. Gray Demon Whales were simply too massive, allowing them to store far more Spiritual Energy than other Soul Beasts.
It was this very trait, combined with their thick, tough hides, that allowed them to carry hundreds or even thousands of creatures on their backs through the perilous storms of Subspace.
Ordinary attacks couldn't harm them at all, though it was also difficult for them to evade.
The Alataku People had another school of thought for raising them: using them as Soul Beasts to attack enemy capital cities. They would be trained to learn devastating Soul Techniques, making them the equivalent of strategic nuclear weapons on Blue Star.
