Meanwhile, Night's Watch lord commander Jon Snow has ordered Samwell Tarly to sail to the Citadel in Oldtown to train as a maester and warn the Seven Kingdoms about the return of the legendary hostile beings known as the Others. Sam is accompanied by the elderly Maester Aemon, the wildling girl Gilly, Gilly's newborn baby, and another Night's Watch member, Dareon. After the voyage is underway, Sam realizes that the child is actually the son of the wildling leader Mance Rayder, swapped with Gilly's real son. The party becomes temporarily stranded in Braavos when Aemon becomes sick, and Dareon absconds with their money. After learning that Daenerys possesses dragons, Aemon concludes that she is destined to fulfill a prophecy, and he needs to go assist her; but shortly after the party finally leaves Braavos, Aemon dies at the age of 102.
