What I would like to know, how did Wanda even know that spell existed? Gossip alone? And how curious that she would offer the chance to buy it to Stanley just when he needed it the most... and talked him into accepting the pitch. At least, it becomes so when you examine the hints from the Grand Abbie that suggest that the Perfect Warlord is meant
to break things and talks Sizemore into becoming Parson's supporter and trying to become his friend. The web is beginning to seem quite tangled indeed. Wanda has almost certainly been plotting to acquire the Arkenpliers even if she did not know it would be specifically them she would get; did someone deliberately tell her about the Perfect Warlord spell to unite her with Parson?
A strange possible causality chain has popped into my mind. Grand Abbie decides to make a supreme effort to create peace. Grand Abbie allies with Predictamancer. Predictamancer plots course and hands Wanda the prophecy that sets her on her
path. Masterclass 'mancers of the Magic Kingdom create the summoning spell. Existence of summoning spell is revealed to Wanda when her Side is backed into a corner...
I am beginning to believe that Parson is something much bigger than a mere Arkentool. And I am mildly amused by the idea that the Arkenpliers are somehow 'game breaking' when the Grand Abbie to me seems to want
to break the game.
