Wrath told Nick where he had to go, and finally, Nick found out where he was.
He was in the western part of the Grand Continent. More specifically, he was between two very big bodies of water, which were around the same size. If he walked a couple hundred kilometers to the southwest, he would be entering the northeastern parts of the War Continent.
Nick knew the continents and what the world looked like, and with this information, he could finally go back to Aegis.
He just needed to fly towards the west for a couple thousand kilometers.
Even more, Nick wouldn't even need to be afraid of Wrath.
On his way to his mission, Nick could just fly to the west, and he would arrive at Aegis' headquarters before Wrath even realized that Nick had betrayed him.
His path home was open.
However, Nick decided against returning to Aegis for now.
