The Legend of Oblivion

A long time ago, there was said to be six objects that contained unimaginable power.

These six objects were called The Objects of Oblivion. They were all held by one ruler, simply named ████. He created these six objects to keep the world in balance, each playing a role. He held 2 of these.

The followers of ████ did their best to protect these objects, as they protected them, but soon people grew hungry for power, and overpowered the followers.

████ took the objects, and used all six to stop the entire universe from self destruction, but the power of all six objects took their course, killing him.

Dungeons, placing mob spawners and a boss to guard the objects. The only one who survived the blast from these objects, was codename "qljkwvfbwkh1987". All that remains of who this legend was are the words "Three Letters Back."

Trivia

 * "Three Letters Back" refers to the shift of the ceasar cipher to decode the codename mentioned in the book. Applying this to "qljkwvfbwkh1987", ignoring the digits, returns "nightscythe1987", the name of the server owner at that time.
 * He has since renamed himself to NightScythe1, effectively making this cipher nonsense.
 * The coordinates given at the end of the book lead to a teleporter to the Sky Temple.
