Instead of taking one of the exposed eggs, you search around in the basin until you find a smaller, hidden clutch. Skycaller examines the eggs briefly once you find them, then nods.

"These Chanis are known as the Shadowed Ones, for their bodies are a uniform shadowy gray in color. Only their wings, ears, and the fur at the end of their tails has color, and even that is darkly colored. The Shadowed Ones are also much smaller than a regular Chanis, all of the colors being in the range of a foot to a little over a foot and a half." So saying, he watches as you decide whether to take one of these eggs, or to continue on searching.
If you take a Chanis from here, please provide a link back so that others can find a companion as well. Naming conventions are given on the page with the image, but keep in mind that those are only suggestions. Also, you can have either the Chanis choosing to tell its companion its name (like a dragon at impression) or you can have the companion name the Chanis.

If an agency owner doesn't object, the Chanis can be turned into candidates, but since they're generally small in size (none of them get to be over 3 feet), I would suggest not sending them in for huge dragons.
