With the registering of each individuals magical affiliation and the snapping in place of those dark metal bracers the group experiences something they have not in a long time, if ever.
Arjaak, Karg, and Ulfgar feel a stark emptiness inside as they become completely disconnected from their source of magic and their patron and the world takes on a much grayer and uglier appearance.
Belgar'ath experiences something similar in that his connection to the Weave that flows through all things gets shutdown, and that bracer becomes an annoying irritant next to his skin. Like a thousand misquitoes all biting at once.
Amos on the other hand initial experiences a peace he has not known for a long time, however this quickly turns into gut wrenching pain that begins mildly but then begins to slowly intensify.
With everyone secured the guard says, "Okay, follow me," and begins walking towards the fort. The guard leads the group across the bridges expanse and the group is followed by two other guards. Below the bridge is just cliffs and dark water. On the opposite side is a wooden palisade with a gate that is about half the height of the Forts 30 foot walls that encloses the area directly in front of the gatehouse itself. The stark difference between the wood and the old but very solid looking stone is quite noticeable making the palisade seem even more inferior than it is. This little courtyard of sorts is filled with a handful of men, numerous small barrels holding ammo and even a small catapult. However perhaps the most noticeable things within the courtyard sit just inside the gate on either side, a pair of sturdy tierces (aka @40 gallon barrel) painted bright red.
The group passes through this little courtyard uneventfully only drawing some glances from curious guards. They then pass under the open exterior portcullis through then gatehouse and then under the interior portcullis. Those experienced in castle design could easily see the the murder holes and ceiling holes used to decimate any trapped units. The gatehouse opens into another courtyard that surrounds the 3 story fortified stone building that sits in the middle. If there were stables they were most likely around back because they could not be seen from here. Sitting on the steps of of this building is a old looking Gnome smoking a strange looking three-bowl pipe, he watches the group as they approach with seemingly casual interest but says nothing. The guard leads them up the short stairs and opens the stout door fairly easily and turns to check on the group.
