This is to show how to care for a Sylph, either as a Summon or as a domestic pet.
Domestication
Sylphs had actually been domesticated longer ago than most people realize; however, the only people who owned domestic Sylphs were those of royalty. The Sylph's beautiful and delicate appearance fetched high prices, and commoners really couldn't afford to own one; in fact, in one kingdom, it was illegal for a commoner to own a pet Sylph, as they were considered fit for royalty only.
