After another three days sailing, the party finds their way to another island south of Septimia. On this island, there is another tower. On this isle, the party finds no Tsaesci to encounter, but more intense physical obstacles to avoid harm from as they explore a new tower.
At the top of this tower, there is another crystal beacon, but there is also a brazier positioned amidst the teleportation circle that allows transportation to it and other towers with those circles on them. They meet with an individual; a human by the name of Vanus, who explains he is also looking for the Tsaesci, to get answers. He mentions being part of an organization with one of K.C.'s family and having a son exploring another Spire.
