According to the ancient Faerie Lore of Galorand, the goddess Fionaidhe is often accompanied by her three prized song birds. Birds have always had a close relationship with the faerie folk and simple peasants will sometimes claim to have seen a sprite or pixie off in the distance when it was actually just a simple songbird.
Spotting these birds sitting on a branch is considered good luck according to Galorand folklore since such a sight is often associated with good blessings from the goddess of the faeries. Fionaidhe has been known on occasion to either assume the form of a songbird or to send her three sacred birds to serve as messengers or heralds.
The goddess' birds rarely seem to appear in the same form twice generally assuming different shapes, plumage and coloration with each sighting. They are always beautiful and generally adorned with richly colored feathers of varying hue. A form similar to the bird-of-paradise is often a common shape. The birds have no individual names, at least as far as any mortal is aware, but they are able to speak telepathically to any intelligent being if they so desire. Their greatest magic though is in the power of their song which always sounds quite melodious and ethereal in nature. When the birds sing, they are able to lull any being within listening range into a deep slumber. Creatures not affected by sleep magic are of course immune to this effect. All others must make a successful Wisdom save against DC 22 or else fall to sleep for 1d6 hours.
The birds are said to be completely immune to spells and spell-like abilities and can become invisible at will. If any creature tries to threaten the birds, they will simply become invisible and fly away. Of course, the offending being will surely get a visit from the faerie goddess or from some of her more militant representatives.
