It all comes down to this, in the end. Nothing else matters; not the fierce battle raging around an artificial moon, not the efforts of those on the real moon below, not the endless activity of the universe at large. This one tableau of raging conflict that cannot be seen is all that matters. Darkness and Light swirl around one figure, both sides of the Force seeming to concentrate on this one person and the choice that faces him. Serve or save?
The darkness whispers of oaths sworn long ago, oaths that bind him to the craven figure beside him. You cannot go back: you swore yourself to him and to the darkness. Oaths that were sealed in the blood of children and deepened through further suffering inflicted by his hand drag him down now. The darkness reminds him of everything he has done; the horrors, the atrocities, the one unforgivable act. The pain sears through him again, remembering the day he turned, destroying the one he loved with all his heart. You can never be forgiven for that, never know love again...
But the light calls to him, reminding him of his purpose, reminding him who lay in torment a scant distance from his feet. You are loved: you are forgiven the light softly promises. Your bonds can be broken. You were pledged to the light first. Memories of love and joy fill him, beckoning.
Sudden purity floods his mind, driving away the tendrils of broken darkness.
The all-important choice lies before him, the galaxy hanging on his decision. Serve or save?
In the end, there is no choice at all. In the end, he can do nothing more than what he was destined to do.
In the end, he chooses love.
