The imp spots the vampiress traveling through the night and trying to elude him by going up and over buildings. The imp has no trouble following the cloud, and when she realizes that he's following her, she drifts down and into another manhole, a few pipes over from where the party is located.<br/><br/>But again, imps are not stupid. They're conniving, corrupting little bastards, but they always have an extra trick up their sleeves. Still invisible, the imp flies to within a foot or two of a nearby drunken human.<strong>"Go remove that manhole cover,"</strong>it says, using its<em>suggestion</em>ability. The man is in no condition to consider the merits of the commands of a disembodied voice, and staggers over to the manhole, grips the cover, and lifts it up.<br/><br/>The imp rapidly dives down into the sewer pipes, flying one way and then another to find the foggy cloud and after only a moment, it's back on the trail, having sighted the cloud again. Imps can fly twice as fast as the vampiress in her gaseous form, so there's no challenge catching up to it, even with the imp having to backtrack slightly as it had chosen the wrong direction initially. Sensing that it was being followed again, the vampiress heads up another drain pipe too large for the imp to follow.<br/><br/>With defeat almost on him, the imp has an idea and decides to put it in practice. The storm drains in Waterdeep empty into the sewers, so if he can find a storm drain, he could find a quick exit in this area and narrow down the list of possible buildings the vampiress entered. Less than a minute later, the imp is on the surface, invisibly searching here and there for the gaseous form of the vampiress. When he catches sight of it again, made easier by gaining a little altitude and giving the imp a more broad view for its cat-like eyes to search, it's heading toward a specific warehouse in the Docks Ward. He glides up to a window and catches sight of it slipping into a wooden coffin.<br/><br/>Seated near the coffin is a woman in thin, elegant black robes (nearly a dress, but not so fancy) with very pale skin and raven hair. One of her arms is concealed in a black velvet glove and she appears to be sitting, calmly reading a book until she spots the gaseous form enter the coffin. She then slams the book, tosses it aside, and snaps the fingers of her unconcealed hand and begins issuing orders to someone that the imp can't see from this angle. He decides that he's done enough recon to give a good description to Adrian, so he hurries back toward Adrian again.<br/><br/>*  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *<br/><br/>About ten minutes after Adrian stuffs the snake into the pipe, the group hears the familiar meow of a perfectly visible tressym flying toward them. It relates a description of what it saw to Adrian (that is as detailed as my description above) including directions to the warehouse less than a mile away.
