Talk:Whales/@comment-24.182.185.114-20121017033528

It's actually mentioned whales actually wildly diverse anatomies in one of the books. I think.

It's also implied that whales are basically magical. Nobody knows how the oil works, but they're used to provide electricity somehow and the purified oil is explosive.

The Heart also mentions even says their flesh is magical or something in the flooded whale processing areas and that the world will end when the last of the whales have died.
