black hollow ?!

Black Hollow is the terror of the Kethali. There is many a story of monsters that live here, intent on scaring the young foals to stop them from wandering in. In truth, there is nothing wrong. It is no more than an old crater from a meteor many, many years ago that happened to drill into the earth in such a way that it left a big, gaping cavern that has since overgrown with grass and vines, making the inside pitch black. It would make a good shelter for a great many horses if the occasion arose.
