Step-by-Step Guide

1. Place two ornate, golden wall sconces on the left wall, ensuring they cast magical light symmetrically across the hexagonal floor. Center a whimsical gilded portrait between the sconces, slightly above the midpoint.
2. Install two arched windows on the back wall, evenly spaced from the corners. Position a simple wooden wall shelf below mezzanine height, populating it with three vibrant books and two magical potions.
3. Add a wooden staircase on the left, aligning its base at the front-left junction of the checkered floor. Attach a wooden railing along the mezzanine edge.
4. Position a charming cat figurine and its broom on the mezzanine. Furnish the under-stair nook with a small ladder, scroll bundles, and logs, centering a robed character within.
5. Arrange three sturdy wooden desks and matching chairs in the main classroom area, adding desktop accessories like potions and books.
6. Place a wooden counter in the center, adorned with three colorful banners and a merchant cat figurine on top.
7. Position a large cauldron and floating runes in the magical corner. Arrange a reading cat beside the cauldron, adjusting elements for visual alignment.
8. Transform the upper right corner with a sorceress pedestal, a plant-laden table, pumpkins, mushrooms, a ghost, and a tomato scroll, ensuring thematic consistency.
