It hasn't been that long since Rezen entered the Tryst Academy and he was making swift progress. He thought that in his journey inside the academy, although he would face danger considering his lacking background and the normal struggle for resources, his life would still be relatively peaceful
He didn't expect that in just a few months, the situation would drastically change. As the magic beasts are now focusing on destroying humanity inside the City of Hope, fleeing from the city and becoming a tribesman again might be safer
However, Rezen is unwilling to do that. Resources can be ignored a bit as Rezen can slowly find them outside but for magical knowledge... only the City of Hope has the best of such things!
Small and large tribes might have them but they are definitely far inferior compared to the City's accumulation
