"The Composer! So many possibilities and capabilities tied up in that strange name... A Composer of minds and souls!"

Forthencho, Lord of Admirals

Composition

Oh, look how my subjects all tremble.

Oh look as their hearts weep and break.

Oh look at the machines that await them,

Constructs with terror in wake.

…

Oh look at the human race humbled,

Their taint's been removed from the stars.

Oh look at the Flood's deadly foe,

Their infection shall never get far.

…

Oh look at our foes' final moments,

Oh look at the fear in their eyes.

Encased in their tombs of our knights,

Knowing their spirits shall die.

…

Oh look far ahead, the battle's been won,

Yet too has the battle been lost.

Oh look as I retire to Requiem,

To evaluate the terrible cost.

…

Oh look as our old foes return,

Their taint has returned to the stars.

Our knights and our crawlers and watchers,

I doubt that they'll get very far.

…

Oh look as they crack open the tombs,

See what lies under the shell.

Oh look at their minds, their anguish delightful,

Just like Charum Hakkor's hell.

…

Oh look as they fight to survive,

Oh look as I string them along.

For I am the Composer, I write this tune,

And I'll sing our foes' final song.

Kind of shooting in the dark here, but hey, if the Prometheans seen in Halo 4 are indeed former humans (akin to how Chakas provided the basis for Guilty Spark), then I can say I called it...or something. At least the achievements suggest that the Composer may be in the game.
