Van Osten's Moon, actually a planet despite the name, is a rocky craggy wasteland with a thin, cold, gritty atmosphere. The planet's geology had been altered in an unusual way. The rocks had deteriorated in a manner suggesting geologic ages. The rock layers, however, had been transformed "virtually overnight". The walls had been altered to become glassy and had embeddged gems. The world bore strange ancient ruins which combined artificial and natural features. The builders had even crafted canyons and mountains.
