I think for sake of argument (and because I think a few messages have separately been sent around), you have brought Nowhere back to Daring Heights because frankly you won't hold him anywhere else.
However, before any of that, there's something else for you to consider as you all stand around with Nowhere's unconscious form. Loot. And Loot you all may find interesting.
-The Longtooth Staff - Granny's twisted staff grants +2 AC whilst held and can have up to three small items orbiting around its head.
-1 Potion of invisibility
-1 Potion of Superior Healing (8d4+8)
-1 Potion of Speed
-A horn which casts Animate Dead 1/day
-Keladry had amongst her personal arsenal a wooden light crossbow +1, which has the Enplacement ability, meaning it can be placed in a position and given a command to attack on a certain trigger, similar to the Alarm spell.
-Amongst the many corpses around you quickly amass 7,000 gp worth of goods (583 each). Notably there are additionally three large rubies which orbited Granny's staff. Now that they are not spinning around, it is quite clear that they each have a small figure inside them.
Two are the dried, dead husks of hags. Some of you will recognise them as the other members of the Longtooth Coven, Granny's sisters.
The third contains the emaciated but still living Viscount Willum Daffles, Mayor of Daring.People inside them notwithstanding, those 3 gems are worth a further 1,000gp each.
You cannot communicate with the tiny man in the gem, nor can you see any immediate way to break it.
