Your real name is a mortal name. Now you need one that is immortal, the one that takes the high stage and plays above the rest. You can't be immortal and mortal at the same time.

The fear of Mortality is the base of Immortality

Aging is a mortal term that my immortal spirit doesn't quite grasp.

I’m an immortal. But I don’t want to be one anymore. Or rather, I don’t want to be an immortal stuck in a mortal world anymore. There is something greater out there for me, but in order to get it I need someone to put an end to my life in this world.

Hope is the last thing that dies.

Maybe because hope is one of those dratted things that is truly, honestly, genuinely immortal.

Shall a man
grave his sorrows upon a stone when he hath but need to write them on
the water? Nay, oh /She/, I will live my day, and grow old with my
generation, and die my appointed death, and be forgotten.
