Having food to eat greatly helped Toz and the cats relax as they continued drifting around the Void. Although they had no control over where they were going or how far they were going to travel, they decided to enjoy the trip instead of worrying if it would ever end.
And after encountering another group of fish, it was beginning to look like the Void wasn't as empty as the group had feared before they ran into the first group of fish. Without needing to worry about food, Toz and the cats spent their days idling around and training mostly. There wasn't much else to do after all.
Though when Toz or Nil got bored, they started playing around with expanding their island of trees using metal. Even though it required regular resupplying of mana, it was nice having some more space to play around on and get some privacy.
Eventually, as the group continued floating in the Void and time passed without any signs of existence other than void beasts, the trees started growing.
