A fantasy underwater common room with dark stone walls, glowing blue lanterns, fish swimming outside large round windows, and a blue-flamed fireplace.

The Shark common room is hidden deep beneath the school near the water. The walls are made of dark stone carved with waves and sharp fin shapes. The ceiling looks like the ocean, with blue light moving like water above. Soft glowing lanterns light the room in shades of blue and green. Large windows show shadows of fish swimming past outside. Comfortable chairs sit around a fireplace with pale blue flames. Silver banners with a shark symbol hang from the walls. The room feels calm, powerful, and watchful, like the deep sea. See more
