Jimiverse
The descriptive term or name of the online "universe" of writings by a fan fiction author, pennamed Lampito. The Jimiverse is based on the CW television show "Supernatural", albeit with the Supernatural characters as well as some of the author's own creations including a Hellhound named Jimi who was "adopted" by the Winchester brothers, Jimi's Alpha is Dean, his Second is Sam.
My wife introduced me to the online fanfic stories of the Jimiverse and now I'm hooked.
