A tall, perceptive Troll that was guarding an old stone bridge across a ravine to the southeast of the dome. Relatively well-kept (for a Troll) & jumped up alert as soon as approached even though the party was silent & invisible, seemed to know how many people were nearby.
Asked for a toll of 5 sp/1 gp or a gift of meat in order to cross his bridge, says all the territory beyond has been 'Claimed by the Ashlord' & cleared of Kobolds.
Wax teleported across the bridge instead, and a confused Rajju just shrugged it off eventually saying well, he no use bridge. Said he worshipped someone called 'The Mockery' one of the 'Dark Six' but didn't seem particularily Evil, more just a hungry, bored guard.
