A common saying captures it well: height determines your horizon, and your level determines the scenery within that horizon.
This saying fits perfectly in the Wizard World.
Just like at First University, standing at different heights results in vastly different vistas. For example, from the perspective of a Big Wizard, one sees the brilliant, boundless starry sky above, while a Trickster gazing from their position can only spot whether fierce beasts are roaming the edges of the Silent Forest a hundred meters away. Likewise, standing on the surface, one can look up to see the sun and the moon, down to a soft lawn, in the distance the Silent Forest, and nearby the bustling marketplace; whereas below the surface, one can only encounter a dark and gloomy world.
This dark and gloomy world is built amidst a maze of crisscrossing sewers and secret caverns eroded by Earth Dragons. And the masters of this world belong to a group of clothed mice.
