What could it be?

I shall get myself a Great Dane in the not so far away future and name him Sir Rufus Van Barkers. To make it less formal and stupid, Rufus for short.

Feeling like a phantom on stage,
A ghostly shadow of my human self,
That had traveled away from the labyrinth,
Released from the mausoleum,
Every move being watched by the world below,
Thousands of spectators gather to watch this materialization,
The story unfolds magnificently,
As I play my part in the story line,
Every mistake to be criticized,
To be marked and judged,
Every prodigy to be awed,
To be applause and spoken of,
It was all about being philosophical,
It was all about pretension,
They could never sequestrate my faith,
Take away things strongly believed in,
Strutting and walking on stage,
Embracing the time given,
A life liven behind the mask,
Hiding a veritable self behind,
Who had promenaded the stages as someone else,
As witnessed by spectators down below,
Someone to be venerated,
Whose name will live forever,
Whose facade that had been a face,
Will be remembered for sempiternity,
Whose torso will be a remembrance,
Preserved in minds for eternity,
When valediction is finally called for,
Lights dim and curtains fall,
A great maestro on stage was over,
An end to a great virtuoso.
