Parallel World

A Parallel World is a world that serves as a parallel or counterpart to the 'other world'. In "Welcome to My World", it is revealed that there is a parallel world where moralities are reversed. It exists to maintain the cosmic balance. When powerful teenage witch Kat Martin and her Warlock-Mortal hybrid boyfriend, Damian Cooper entered an Parallel Universe, they met their counterparts and were shocked to learn of their identities.

Overview
In the world where moralities are reversed, Kat Martin and her family are powerful evil witches and the terrors of Los Angeles, feared by all. The Serena Spellbook is also an evil counterpart. Parts of L.A. has been reduced to a slum while only the manor remains intact and unchanged.

Leo Wyatt and Sam Wilder are Darklighters instead of Whitelighters, resulting in Paige, Wyatt and Chris being born as Half-Darklighters. Additionally, in this world, Chris came back from the future to save Wyatt from turning good instead of evil.

Gideon is a dark Elder in this world, though it is unknown whether there still is a council of Elders.

The San Francisco Police Department is corrupt and a rogue Darryl is shown hanging out in P3, which is a strip club where Inspector Sheridan moonlights as a pole dancer.
