You are one of the hundreds of sorcerers aspiring to immortality, but defeated by the inexorable pass of time and your lack of ambition. Your name will not be remembered.
You made it. Your immortal soul will linger in this world forever, just enough time to discover all the secrets of the cosmos. Your body may rot and wither, but you will find younger vessels as the ages pass by. The world is now yours.
Time doesn't have meaning anymore. Ages come and go, empires rise and fall, and you stand above them all while researching the most corrupting secrets of the void beyond reality. And with a little luck, you will become a god.
