Jack continued practicing until Peniel told him that they were close to the coordinates. He was too focused on the training that he lost track of time. If Peniel didn't remind him, they might have arrived in Hraghshu's manor without realizing it. They were around one hour away.
They didn't see Tenka or Yrin on the way, which meant the two were still ahead of them.
Jack told Pandora to not run directly to the coordinates. They couldn't afford to barge in the manor just like that. They first had to covertly check if there was a teleportation chamber inside the manor.
