Before time / Before the Universe

 * Before time itself, ancient beings of darkness and light ruled the void between universes. Darkness incarnate, known as The Beast, was a being of temptation, sorrow, anger, destruction and the death of hope who has fought against the Disciples of the Light. The Disciples managed to imprison The Beast in the center of a planet called Krop Tor orbiting around a black hole. The Disciples rigged the planet so that if The Beast were to escape Krop Tor, the planet will loose it's gravitational orbit with the black hole and fall into the event horizon. Over time and after the Big Bang, the legend of the Beast lived on in the universe after the death of the Disciples which inspired the beliefs in religious figures across the universe such as Lucifer or Satan and many others.

Events dating back and forth through time

 * At an unknown point in history, an ancient race of aliens called Time Lords fought in a brutal war with each other at different points in history and even used time as a weapon in their battles with time loops and temporal paradoxes. This was the first Time War. A second war broke out a generation after the rule of Rassilon and lasted for 30,000 years. Instead of each other, the Time Lords fought against other races developing time travel such as the Charon who the Time Lords had destroyed. Later, the Deindum War started as an attempt to erase the Deindum from existence before they develop into a war-like race. As another war between the Time Lords and the Daleks began, a single Time Lord known only as the Doctor decided to destroy the Time Lord home planet Gallifrey in an attempt to eradicate the Dalek race during the Last Great Time War. Unfortunately, after an encounter with his future selves, his decision of committing genocide was averted and he and his future selves decided to keep Gallifrey alive by having it reside in a pocket universe trapped in time. In the midst of Gallifrey's transportation into the pocket universe, the Doctor escapes by stealing a Time Lord ship called a TARDIS and deciding to live out the lives of his future selves and travel throughout time and space.

 * A big bang occurs (general scientific belief of the universe's creation), this big bang was caused by Azathoth. A giant amalgamation of limbs, eyes, and mouths floating through space who is a cosmic deity whose very existence caused the creation of the universe. Azathoth later brings three sons into existence: Nyarlathotep, the Nameless Mist, and the Darkness. As Azathoth continued creating and destroying many worlds in the universe, his sons created minions and devised a plan to put Azathoth in a sleep like state and put a halt to his chaos. They succeed and overtime, give existence to Outer Gods such as Cthulhu which have the same cosmic god-like status as Azathoth and his sons. These Outer Gods then bring life to various Great Old Ones who bring life to various alien lifeforms on other preexisting planets. (H. P. Lovecraft)
