Remus, James, and their new companion left the streets of Hogsmede, and continued into the stretch of forest beyond. They soon came to a clearing with a very homely looking camp set up, which included the largest tent James had ever seen.
When the man from the pub saw James' astonished gaze in the direction of the large tent, which was rumbling ominously, he chuckled a bit and said, "Ah don't worry about Grawp, he won't hurt you, he's a nice giant."
"So can you get us the things by morning?" Remus asked the man.
"Sure thing mate." He replied, "Extra tent's for you two. 'Night." And with that, he headed over to what appeared to be his tent, and vanished inside of it.
"Who is that?" James asked as he followed Remus to the extra tent.
"That is Judson Weasley, biggest black-market tradesman in Europe. He's getting a wand for you, and brooms for both of us, so that we can go save the princess tomorrow.
And sure enough, the next morning, James ventured from his tent to find Judson with his arms outstretched, one holding a wand, and the other holding a broom. In the ensuing moments, James was instructed in proper broom-riding techniques, introduced to Grawp, and informed of the plan: Remus had been informed of the location of Azkaban Prison by an old friend, so he and James would fly there, and Judson and Grawp would approach as well, from the other direction, thus creating a diversion.
Once everything was set, they flew off toward the north. The flight was to be long and boring, so Remus took it upon himself to teach James the Patronus charm on the way so that he might ward off the evil Dementors of Azkaban.
Everything went according to plan when they arrived at the prison, and the princess was saved. However, Sir Prajottham had apparently been informed of the attack on his prison, for he arrived just as James, Remus, Judson, and the Princess were leaving. Remus signaled for his companions to retreat, and engaged himself in a duel with the dark, hooded figure before him. The duel was quite a wonder for James to watch, having never seen anything like it before, but to his dismay, dark triumphed over light in this particular battle, and Remus fell. James made an attempt to rush to his teacher's aid, but the princess had already grabbed his wrist and was dragging him toward the tower in the distance that was Grawp.
