Tinker Tock is a high ranking Solar officer, close to Celestia in more ways than one. He's gotten to this position by way of his own cunning (and a fair bit of backstabbing). He is, without doubt, one of the sun princess's most trusted ponies aside from Twilight Sparkle.

What she doesn't know is that he has fooled them all.

Tinker Tock truly belongs to Luna's Republic. He's in deep, and the only way out is through the death of a leader. But can he do it, now that he's been in deep for so long?

EDIT: Cancelled due to a shoddy storyline, and a lack of coherent continuity.
