At least one person agreed with me about the anticlimactic ending to Richard's escape from banishment. As I don't believe LFG would censor its readers, I have to assume Richard is somehow behind this, he is after all a Dick.
As for Richard v. the Sisterhood, I believe he was aware of the summoning, though possibly not the target. Then again, the fact that the Sisters worship a rabbit and that Richard has yet to eat or otherwise dismember one he travels with leads us to believe that their maybe something more to the rabbit than meets the eye.
Perhaps the rabbit is a mascot of the sisterhood and used its powers to confuse Richard.
