The Citadel's North Tower is atop a spiralling staircase that would be quite daunting to anyone that doesn't live atop a mountain, which is why in the centre of that spiral there is a newly-restored system of pulleys and counterweights to lift residents, visitors and cargo to the lofty peak. The room awaiting you at the top is a chaotic jumble of a room, being part kitchen, part reading room, and part shrine, with the windows on each wall firmly blocked by thick curtains to keep the heat in. Thick rugs cover the floor, cushions are strewn about in place of chairs, and a softly glowing ball of Shyish provides illumination. You give a carefully respectful bow to the shrine - a haughty-looking raven perched atop a skull, carved from stone - and busy yourself investigating the half-filled shelves. The books on Morr and Shyish you expected, but you do raise an eyebrow at the books on ritual magic, as do the ones on Tilean history.
There's a creak as a trapdoor in the roof opens and you turn to see Gretel climbing down the ladder on the wall next to it. "Magister," she says to you in greeting.
