From the air, I saw this island, set in a jet-black sea.
Its coast was bounded by shimmering cliffs, coves, small peninsulars & islands, whose surfaces were clad in broken, shimmering crystal rocks,
Inland from the bordering cliffs the whole landscape consisted of tightly packed conical, sharp-summited, volcanoes, whose fine grained ash & pumice tumbled down the slopes in feather-like patterns.
All were topped by a black hole where each had, many eons before,ejected there molten contents to the land.
The lower I brought my craft the more detail I was able to see & at which I found it impossible not to marvel.
