The 'door' to his domain stood, while not open, unguarded. The many wards and protections built up around it had long since been torn down, or, worse, triggered by brute-force attempts to enter. In any case, it was much like entering a burglarized home, the impression made even stronger, once he steps inside. Without his guidance to shape and repair it, the battle scars from both the break ins, and subsequent struggles held here, are visible in the main rooms of his domain, as he starts moving through it. It's been fairly thoroughly ransacked... though he can still feel defenses, humming, deep inside. A few minutes of travel, and he'll find the door to his more secure labs, still intact, wards and all; they've never been breached, though the remains of many attempts, and attempters, are visible around it.
