The first spell that caught Wolfe's attention was the [Generational Farmhouse] spell. It was a layered Earth Magic array, and it was intended to precisely what the name suggested. It would create a house that was designed to last more than a generation of Demons.
The designs that were included in the description of the spell were all for simple stone houses, with slate roofs and stone floors. In a hot area like most of the Demon Realm, they were perfect, well ventilated and bright with well-placed windows.
But in the Frozen Wastes, they could be a bit too breezy in the winter, and the floors would always be cold. But the windows could be upgraded to double-pane with glass or air magic, and the floors could be heated or covered with a rug.
Being able to use the template would allow Wolfe to make these houses in under a minute at his level, which would be perfect for making homes for an influx of new residents like they had received lately.
