As they agreed, Zuline modified Jäwell's shadow to prevent the undead from taking him as a target. Inspiring fear in every night creature that would cross his path, he would be safe from them, which was not the case for Sarin.
On their journey to Akshren, they were attacked no less than seven times. Jäwell and Sarin were exhausted before they even joined the outside wall of the city. They had to progress slowly, and by night, to not be taken by surprise when the undead were active.
When they reached the main bridge to reach the city, they had to take a boat to cross the river and make a detour to be able to avoid the massive column of creatures. The little barge was threatening to sink any moment as Jäwell and Sarin paddled discreetly in the night. Looking at the creatures from a distance.
