A god like figure that is the manifestation of all that is gnar; the most commonly prayed to deity of all religons; known by all for his blood lust, void like aura of non emotion, and unparalleled guitar playing skills. His life long mate is also origined from the gods, and is known for her seductive beauty and epic blunt rolling. It is said that reality was shredded into existence through his hardcore guitar riffs on the legendary Gibson Les Paul (referred to as "pegasus"). Theologists claim Jimi Hendrix sold his soul to Lord Rinnie in exchange for Gillion-like abilities on the musical "Ax". His origins are shrouded in mystery and secrecy. He was created by a being known as "the rogue Ron". A being so ancient and enlightened, he does not exist on this plane of reality.
Me and, my grandmother used to walk these country roads with good ol' Rinnie Gillion.

In the name of Rinnie Gillion, amen.

May the Rinnie be with you.
