Who is howling at House Delzuld?

[O-louth]

In the early hours of the morning, strange howlings can be heard from House Delzuld. Travellers up the northern road, talk about whether "Lord Delzuld forgot to feed his hunting hounds?!"
The few guards of the house seem far more alert than usual, while bickering through their breath, that "That damn retainer is bleeding insane".
