@Golem: Hmm... I haven't talked with Rin about everything yet, but the one thing I can point out is I know for sure that some religious organizations/groups in general would be opposed to the use of formerly-sapient undead in that way for a variety of reasons.

@Cake: Alchemy is in the first post, and it is not magic.

Also, um:

Creature Name: Skywhale
Creature Appearance: [url=https://www.weasyl.com/~xenoximen/submission/77033/xenoximen-wailord-1054998.png]Like this, but in the sky[/url]
Creature Description: Skywhales describe a small number of species of giant, flying mammals. They fly using giant airbladders carried inside their bodies, which allows them to drift through the air. They can siphon gas in and out of their airbladder in order to raise or lower altitude. Skywhales feed and drink through very unique methods. The immense creatures consume whole clouds for moisture, and they feed both by absorbing sunlight and consuming vast swarms of tiny flying creatures. Skywhales are placid creatures by nature, proving to be harmless to airships unless their is a collision. However, they were hunted for a long time for their airbladders, which were used in earlier airship designs in order to provide them with a method of lift. They are also still hunted by some cultures for their meat. Rarely, skywhale calves are sometimes available for purchase, alive. The only natural enemy for adult skywhales are western dragons.
