The ideal lair for a blue dragon contains multiple passages, rooms, and secret chambers. As social creatures, blue dragons prefer to host guests in comfort-but their dwellings should not be so public that just anyone can come calling. A force of guards keeps out intruders, and clever illusions conceal the edifice from prying eyes. Rather than a pile of coins or gems, a blue dragon's true hoard is the rich furnishings in its citadel- expensive art, ornate furniture, and architectural marvels.
