Vanetin leads you into the cave, explaining as she walks, "I have an egg here, though it's not Hatched yet.  It is a Chromium Dragon egg.  They've been extinct for a thousand years, and Myrror is apparently trying to get them circulating again!"  She smiles, gesturing to the egg, nestled in a wallow of sand, "So I'm doing what I can to help."  You see the egg, and think it looks very tiny compared to the others that you've seen, but it's still very pretty.
 

Vanetin smiles hopefully, "I hope it hatches.  It would be a shame if the Chromium dragons continued to be extinct."  With a small wistful sigh, she leads you back the way you came, "You can come back sometime, to see if it Hatches."  She goes through the door.
