"The Watch is Coming" quest is solved in Knight's Tomb in Dark Forest.
You could either send the Watch to Cyseal or tell them that imps are at Homestead. If you choose the former option, you need to meet them in Cyseal. If the latter - just talk with the imp called Dark Underlord at Homestead. Or is there any other problem with this quest?
Myself, I couldn't finish "Lady in the Lake" (I didn't get it. What was I supposed to do?), "Prisoners in Crystals" (or whatever, I don't remember the name. It's in Hiberheim), "Frederick's Blood Stone" (He was dead after I gave the Courage Potion to the Imp) and the Whiskey Quest (I found the book with recipe first and when I 'made' Whiskey, I already killed bartender. Due to "Armory key" quest).
