Descriptions are very similar to that of the other gryphons, with a few adjustments.
Egg
Spoiler
This egg has two small wings protruding from the shell, and has faint spots.
Spoiler
This young gryphon has gray wings which will grow to be white with black tips, and a silvery black-colored body. It is already beginning to fly short distances, and makes screeching sounds when approached too quickly. Becoming more muscled with each passing day, it consumes rather a lot of meat, although now it has become used to hunting on its own, disappearing for long hours and returning sated. This youngling has its first tail feathers and small talons, and already is trying to copy its elders, taking small hops and extending its wings.
Spoiler
Your pet has matured into a ferocious, incredibly powerful adult. With thick talons extending for several inches, an iron-like beak, and an impressive wingspan, this is a very formidable beast. It hunts for deer and other large game, as well as anything that threatens its territory. Greater Gryphons love to play with each other, seeing who can fly the farthest, and other harmless entertainments. Greater Gryphons are larger and stronger than the other, more common varieties. This fully grown gryphon is now strong enough to carry two people plus luggage as it flies, provided they are kind enough.
Spoiler
Gryphons are noble and majestic creatures, and their eggs are not often come by. Gryphons nest high in mountains, and protect their young fiercely. If an egg is acquired, it was through permission and not theft. These creatures live for hundreds of years, and are wise, powerful beings. If a master is kind and loving enough, a gryphon may even allow them and a mild-mannered friend to ride it.
