Chaos lords roamed since the beginning of time, causing chaos and mischief around the world. With an anchor (An object or partner that keeps chaos lords within the mortal realm) Chaos lords are able to stay on earth, unless the anchor is killed or destroyed, the chaotic being will be sent back to its own realm. (In Chaos Midori's case, his 'Anchor' is Midori) Chaos Lords can also possess items or people and make them do whatever the chaos lord wants. If a chaos lord speaks backwards, they are casting a spell or they just want to speak that way. (Which is what was happening in the RP, it was a spell: "Dream Protection" but backwards, which prevents nightmares and any bad moments in dreams, which is what he casted on Camellia after the procedure)
