After eavesdropping on the discussion held by the council gathering, Soran wasn't quite prepared to let his efforts with Vivian thus far go to waste.
One way or another he needed to ensure that Lady Morgana did not proceed with the ritual binding; however, the old witch was as stubborn as a mule.
Nothing would change her mind or her decision.
Even if he thought up some logical reason not to proceed with the ritual binding, Lady Morgana would not listen to reason.
Hence, Soran decided to opt for a different approach.
If he couldn't prevent the binding ritual, then the next best course of action would be to sabotage the entire magical procedure.
And with no time to waste, Soran made his way to the Coven's official ritual chamber. Compared to the desolate, abandoned one he lured Vivian into before, this ritual chamber was far grander.
