This exceedingly detailed work by the doppelganger, Zhoreb Vaigthlu is a magnificent example of a life dedicated to a single task. Zhoreb obviously used his natural abilities to gain access to all of these locations and his work is a benefit to all who read it. Within are long and artistic descriptions of the upper realms and these long prose descriptions are coupled with accurate maps of the most common sectors of all of the upper realms.

In addition to the descriptions and maps, Zhoreb speculated upon the nature of the creation of the upper planes, and it is this section that sages widely agree upon as the most offensive aspect of the work to upper realm creatures. It is not uncommon for creatures hailing from those realms to purchase and destroy any copies of Geography of the Upper Realms they find.
