where does samwell tarly go to become a maester
Samwell Tarly Jon sends Sam to Oldtown to become a Maester, accompanied by another brother, Dareon (who is appointed as a recruiter), Maester Aemon (who Jon fears will be sacrificed by Melisandre for his royal blood) and Gilly and her baby. During the voyage to Braavos, Gilly grows despondent, and Sam realises that Jon had swapped Gilly's baby with Mance Rayder's newborn son lest he be sacrificed as well. Aemon falls ill during the voyage and they are forced to spend their money on a healer and lodging in Braavos. In Braavos, Sam also encounters Arya Stark, though he does not realise her identity. Aemon hears of his great-grandniece Daenerys Targaryen and her dragons, and comes to believe that she fulfills the prophecy of a "prince that was promised", asking them to inform the Citadel. Dareon decides to desert and Sam fights him, before being thrown into a canal. He is rescued by a Summer Islander, Xhondo, who offers Sam and Gilly passage to Oldtown. Aemon ultimately passes away early in the journey, and Sam and Gilly briefly become lovers in their grief.
