Yup. Probably went through with the original plan of the swap and then Myriad probably sped away with the Pebbles, probably because of pushing a random button just to see what it does.
As for patrons, I figure Delja would have somehow tried to swindle Ux into accepting NEVER EVER to talk to that stupid Angel again once the serial killing and totally justified book burning business was concluded; report to the Dustmen; and court their favour by selling them all the dead Obyriths cheap.
Yeah. If you want to use it to close-attack-withdraw in combat, you want the maneuverability. Trust me. Unless you want to do more math than with the Knight stuff, you don't want to melee with average flight.
