Now that the rush of a large custom order was finished, Karl got to work on the items for the city's purchasing agent, and started to plan what he should do with his [Tiny World] spell.
There were so many options, and it could be used for dozens of different purposes, but each of them would require that he set up the interior in an entirely different way.
The best option seemed to be a hybrid living space. While he could enter it, that didn't seem like the most productive way to use the space when he was already advancing faster than everyone else.
With everyone but Thor at Overlord Rank, Karl was already moving steadily up through the power growth range, and the rest of the team had just reached Monarch.
So, the best thing that he could do was to create a training and living area, with water, trees and a large open area for training, plus a house.
