While her khalasar rests in Vaes Tolorro after crossing the Red Waste, Daenerys orders her three bloodriders to scout out the country, each one in a different direction. Aggo leaves to the south-west, where he find nothing but sterile desert and the ruins of two abandoned cities. He is the second bloodrider to come back to Vaes Tolorro. After his return, Daenerys sets him to repairing the gates to defend the town should they come under attack.
