The Avatar met him during an attack of thieves on his house after the latest of his son Leeland's stories actually proved true. Joshua, who was worried about the lies his son had told before, hoped that this would scare his son straight, and then asked the Avatar for help. The thieves had stolen his valuable journal, and he needed it back. The Avatar found it, reading that Joshua was researching the unstable orbits of the Moons of Britannia, before returning it to its owner. Thankful, Joshua gave the Avatar several powerful spell scrolls in return.
