That would depend on the nature of the Oath, eh? By what terms you bound yourself, and to what ends.

[ Softly ] By the highest authority we swore and named them in witness, and to the worst of punishments we bound ourselves should we falter or fail. Words like that have power, Mikleo - and such an Oath should never have been spoken. But speak it we did - thrice did we swear, and so are bound. I... it became a madness. A force of its own that drove us on and on and on, past all reason. I might break it, I suppose - but I fear the Dark that would follow if I did.
