You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input: Passage: It is revealed that following the end of the Norvagen/Draigar war, the Dragons briefly returned to Earth but decided to return to Dragon World and let Humans guide their own paths. Scylla, high priestess and queen of the Odaku army, along with her dragon Slann, summons the Shadow Dragons Gryndel and Daakon.  She offers to open a portal to the Dragon Realm if they aid her in conquering the Norvagen and Draigar kingdoms.
Meanwhile, Norvagen Prince Dev and Draigar Princess Kyra lead a raiding party to take out an Odaku outpost, who have been increasing attacks against them. But as they enter the outpost, the sleeping soldiers turn out to be decoys, and the raiding party is ambushed. The Odaku wear armour that repels any form of attack and they are armed with explosive weapons. Worse, the Shadow Dragons arrive, and take the souls of Targon and Aurora, Dev and Kyras Dragon companions, killing them. Seeing this, Dev goes into a battle rage. Meanwhile, Dev's and Kyras fathers worry about their children, especially Dev, who has shown signs of being a berserker, like his grandfather. After the attack, Dev and Kyra regain consciousness and find the fallen Targon and Aurora. Dev realizes he is losing control of his emotions. A second fleet of Odaku soldiers arrive and Dev and Kyra are left defenseless. A stranger approaches them and offers to aid them, and Kyra eagerly follows him, along with Dev, who is hesitant about traveling with the stranger.
In the dragon world, King Thoron refuses to interfere in human affairs, which is why they left a second time. But when he hears about the Shadow Dragons, he decides to return and finds Targon and Aurora's bodies. Though the other dragons grieve, Thoron knows that when dragons are killed by Shadow Dragons, they create the cosmic opposite, Light Dragons.
Solution:
What is the name of the character who offers to open a portal to the Dragon Realm?
