Complete Locations is an excellent coffee-table size book that gives you detailed information and drawings about many of the locations in the Star Wars saga. So, of course it would include the Rancor pit below Jabba's throne room. The pit is rumored to have been hollowed from a sacred B'omarr grotto and is now littered with the regurgitated bones of the Rancor's meals. Try to remember the first time you saw Luke fight the beast and the disconsolate reaction of Malakili, the beast wrangler. This is an excellent book to peruse at length.
