The Wax King sent Lady Madalena off to gather the other Knights for your assault on Mother When and the Finishing School. He asked if you would go to the Drawn Tower to meet the Scribbler, giving you directions to find it within his domain. The Wax King had a line of folks wishing to speak with him, to mete out judgments, offer sanctuary or hear complaints. You noticed, as you left, that the candle drooped slightly when he climbed the dais to resume his role as a monarch.
The Drawn Tower is an inky black obelisk sticking up towards the top of the warrens, possibly piercing it in places. No guards standing outside, no people, smothered or otherwise, nearby. In fact, all the muck and the mire ends about twenty feet from the base. The edge is a dark blue, like a pen's ink has run a bit into the muck.
The tower, as you get closer, appears like someone took a giant magic marker and scrawled a tower. There are tiny gaps where the marker didn't completely fill in the space, and you can see through it, or into the tower. darker and lighter places of shading along the walls, as well.
As you come to the foot of the tower, this man sticks his head out of a window at the top:"Who are you?"
he calls down, his voice heavily accented.
