The Dranaga common room is as lavish as it is imposing, as it is the only house to occupy an entire tower, and the tallest tower of the castle at that. The vast common room glows with warm light from ornate crystal light fixtures and a towering hearth, its fire framed by an elaborate mantle carved with dragons. Polished stone floors are layered with rich crimson rugs, while deep armchairs and sofas of leather and crushed velvet cluster around low tables of dark wood. Tall windows open onto sweeping cliffside views, their heavy drapes embroidered in gold thread. Along the walls, Pre-Raphaelite-style paintings depict classic tales from Camelot and King Arthur's folklore.
At the center of the room rises a grand spiral staircase, its banisters wrought in gilded ironwork. It ascends through the middle of the tower to the two upper dormitory levels, which ring the chamber as open balconies rather than enclosed floors, their railings overlooking the common space below. High above them all, crowning the tower, is an enchanted stained-glass dome depicting dragons in flight. From the hearth on the lowest level to the dormitories above, its light washes the tower in jewel-toned brilliance as the dragons move within the glass piece.
