Timeline (Mythological Arc)

Dates are tricky in Supernatural. Some dates are significant dates are made explicit in the script, but most are not. Sometimes dates that appear within an episode relate to the the date when an episode was shot rather than when the events are supposed to occur.

It is generally accepted by fans that the time covered in each season roughly corresponds to the air dates e.g. from September/October to May.

Dates here taken from killa's timeline and hells_half_acre's timeline, canon where available and some wild speculation. The episode an event relates to is included so readers can make their own decision.

See the timelines category for other alternative dates.

• The Mark begins asserting its own will and begins to corrupt Lucifer, amplifying his jealously of mankind.

• Lucifer begins communicating with Abel, when Cain realizes what Lucifer has planned he strikes a deal with the archangel: Abel's soul in Heaven, for his in Hell. Lucifer accepts the terms, on the condition that Cain be the one to kill Abel.

• Lucifer passes the Mark on to Cain. Unwilling to become the killer the Mark wants him to be, Cain attempts to kill himself with the First Blade, but is resurrected as a demon.

• Lucifer hand picks humans for Cain to turn into demons (of which include Abaddon), and has him create the demonic order known as the Knights of Hell.

• Having seen enough, God imprisons Lucifer with six-hundred seals, sixty six of which have to be broken for Lucifer to escape his confinement.

• Zeus took away fire from the humans, leaving them dependent of him and defenseless against monsters. But, Prometheus gave it back to them to protect them from the monsters in the world. Zeus cursed Prometheus to die every day, and imprisoned him in a mountain range.

• In the 10th millennium BC Eve finds her way from Purgatory to Earth, and begins birthing the first monsters -- the Alphas, before she is sent back.
