"My, my, my you have such a sunny outlook on things." Wren said with a soft laugh. "I'm still not sold on a necromancer even needing to be involved. These things aren't zombies, they do have ntelligence and can plan...  Perhaps even make long term plans for all we know and intend to destroy Waterdeep entirely by overwhelming it with undead. The city is too large for even an army to take it back with a hundred thousand dead running about... for all we know, it's a demon in charge or just someone who is giving a wight what it wants... there's more than enough anger in them to make the idea of taking over the city worth while..."<br/><br/>She looked at the door again, "If an alarm had been set off, we would of seen a response before we got back... and the door being locked may not of been to keep them in, but us out.  The door cannot be opened from the inside, so anyone who walks in gets eaten... Without prior awareness, even a well armed patrol would get shredded walking into that room... So, that answers a potential question... There's no point in thinking much on it... and who says that a high and powerful necromancer is needed? Hell, a single evil cleric may hold sway over a relatively weak wight... no where that I know of does it say that a wight can't create hundreds of the things all alone without being hundreds of years old."
