The reason I have summoned you all is because your power is necessary to the success of my plan.

I may be able to obliterate the enemy by myself, but since I cannot leave the holy tower, I will need you knights to act on my behalf.

However

I understand that this act will conflict with the oath that you have taken.

Those who will follow, those who will leave

And those who would come together here to defeat me

I shall await your answer by sundown.

That is the amount of grace I am willing to give.
