Their goal was Milford Haven in Wales. This was the place Erik had told Nora and Anna to take the boat to, so that they could meet up there and travel south as quick as possible.
It would take them at least six hours to reach the place, considering that they also had to avoid any populated areas, lest news reaches Alexandre regarding their trajectory.
Not long after they left, Erik got a new message from Katya, saying that Alexandre had left the Council in a hurry after receiving some news from his guards.
She didn't ask after the mission's success, however, because she continued by saying the Council would continue its deliberations, and she had to continue attending, lest she call any suspicion on herself.
Then, she finished by confirming she'd be waiting at the agreed upon meeting place in ten hours.
