Day of Disaster

The Day off Disaster is an event that takes place in Sonic the Hedgehog. It refers to the day Iblis was freed from within Princess Elise whereupon it’s flames devastated the entire world.

Beginnings
As a child of 7 years of age, Elise had the Flames of Disaster sealed within her via a Chaos Emerald by her father after the Solaris Project failed and split the namesake entity into his two forms, Mephiles and Iblis.

From that day onward, Elise was instructed to never cry, as doing so would release Iblis into the world in all its fury and wrath, plunging it into destruction.

Events
Some 10 years later, Elise was victim to a series of kidnappings by Dr. Eggman, who wished to take Iblis from Elise for his own desires, although at the same time, the princess was continuously being rescued from the doctor by Sonic. Despite this, at one point, Sonic was unable to rescue Elise from Eggman, which in turn lead to the Day of Disaster unfolding.

The Day of Disaster itself took place two days after the Festival of the Sun. Elise, with Iblis sealed within her, died while aboard the Egg Carrier, releasing Iblis into the world. With Iblis now free, he was able to ravage and engulf the world in his flames, creating the future that Silver would be born into.

Aftermath
Over 2 centuries later, the world became a barren wasteland of ruins due to Iblis’ destructive nature. Mephiles claimed to the peace-seeking Silver that this day was the responsibility of Sonic the Hedgehog, although in reality, it was nothing more than an accidental malfunction of the Egg Carrier’s engines, and insisted that the only way to save his world would be to travel back in time and kill the Iblis Trigger, Sonic.

Trivia

 * The name of this event may derive from Iblis’ own alias, “The Flames of Disaster”.
