Gondola brought three people to Starlight Island, and when it left, it only took two of them away—Dodoro remained behind.
Angor thought about keeping Dodoro with him, but Maya came to him and suggested that she should be the one to provide Dodoro with basic wizardry lectures. After some consideration, Angor listened to her advice.
Since Dodoro would be staying with Maya, Angor left Dodoro's "luggage" on the island as well, which included the water bowl with the serpent mark. Angor didn't think he was going to discover anything from the object, so he simply returned it to Dodoro.
To Angor's surprise, Dodoro took everything else and gave the bowl back. He said that he wouldn't entrust the item to anyone else.
Angor used voice transmission to ask the reason for it, yet Dodoro couldn't manage to give him an answer. "Something told me this is very important" was all Dodoro could say.
