Volo's Guide to Monsters (in-universe)

Volo's Guide to Monsters was a hardcover book written by Volothamp Geddarm and annotated by Elminster Aumar in the late 15 century DR. "Some of what's in this book is true and can even be trusted."

- Elminster

Description
The book contained information on numerous monsters, from the wilderness to the Underdark. Volo claimed to have personally researched the information related on its pages, either by conducting concealed observation or by consulting with entities such as the guardian spirits of tombs.

History
After publishing the book, Volo traveled to Port Nyanzaru, where he visited several taverns to promote his work. He sold signed copies to the merchant princes and to adventurers for 50 gp.

After finishing his book tour, Volo returned to Waterdeep, where he ran into financial difficulties while he waited for royalty payments from Volo's Guide to Monsters. In order to offset his debt, Volo began working on his next book, Volo's Guide to Spirits and Specters.

Reputation
Annotations by Elminster Aumar found on some copies of the book implied that some of the dangers involved in the field research conducted by Volo were attenuated by Elminster himself informing some monsters of the foul taste of Volothamps.
