First of all, Tarquin is AWESOME!!!! Second, I think Nale is dead. I don't see this as some kind of scheme that he was doing to prove that he's in charge, I think he just flat out killed him. I see it more likely for Tarquin to attempt to raise Malak than for him to do anything with Nale. His son made his decision, obviously not what Tarquin wanted, but he did what Nale wanted and didn't give him any protection. Death does seem like the price for killing not only Tarquin's best friend but also one of the members of the troupe. That's how I see it at least.
I am thinking that there goal is to have all of the gates destroyed, it must not have anything to do with the Snarl, but in some way it may help them. And I don't think it's going to be about shutting down V for five minutes, like thejeff said, it stop her from stopping Roy from not destroying the gate. Also, the other two have a much longer amount of time they can keep V contained or out of commission. Dum dum dum DUM!!
I don't really have anything to add to this one, except to say I really like the idea of some off the wall and un-serious adventure that accomplishes nothing but to get a lot of laughs. There's always the idea of the ubber-wizard who just has one too many screws go loose and decides to make a dungeon filled with cream pie traps, pits of pudding(edible kind, not the killer ones), and the only way he will let you win is if you can beat his best creation in a snow ball fight, then we will stop sending out his rubber-band made and sized golems out into the country side to trip, shoot paper wasps, and mess with people's lives. I don't know what any of that means that I just said, but it made me gaffaw, so I like it.
